1. "If you’re stuck on an annoying call, put your phone on airplane mode instead of just hanging up. The other person will see 'call failed' instead of 'call ended.'"
2. "When you sign up for anything online, put the website’s name as your middle name. That way when you receive spam/advert emails, you will know who sold your info."
3. "Always tell a child who is wearing a helmet how cool you think their helmet is. It will encourage them to always wear it in the future."
4. "When you don't have all the facts, try to give people the most generous reason you can for their behavior. Annoyingly slow driver? Maybe it's a mom with a birthday cake in the back. This mindset will gradually make you less reactive and more compassionate."
5. "Do not try to be the man your father would want you to be. Be the man you would like your son to be. It more clearly defines your own convictions, desires, goals and motivates you to be your best."
6. "When a friend is upset, ask them one simple question before saying anything else: 'Do you want to talk about it or do you want to be distracted from it?'"
7. "After a bad breakup, do 10 things that your ex would never do with you. You'll feel better and realize how much of yourself was being held back."
8. "Before you give your child a unique name, try it out first. Use it on food orders, reservations, appointments where applicable, etc. It’ll give you a glimpse of what they’ll deal with when they’re older and could prevent future issues."
9. "If you need to cancel a hotel reservation but are unable to because of a 24-hour policy, call the company and move your reservation to a later date. Call back within a few days and cancel for no charge."
10. "If you tell someone you need to talk to them, for the love of God give some indication of what you need to talk about, or at least that it's not bad news."
11. "Never send a work email when you’re emotionally compromised. Type it up, save it as a draft, and walk away. Ideally, sleep on it. You’ll make a smarter choice when you're not heated."
12. "Don't just let kids win at games. You can slow it down, you can teach them strategy, but keep it real. Someday, they will beat you fair and square, and it will be a moment they always remember with pride."
13. "When cooking things on aluminum foil, first scrunch the foil up, then lay it loosely flat again out on your baking tray. The juices will stay put—and the food will not stick to the foil half as much, if at all."
14. "If you think of a good idea, write it down. Your brain will try to trick you into thinking you will remember it later, but it's a liar! Therefore: Write it down!"
15. "It takes 4 minutes a day and almost no cost to maintain dental hygiene. It takes a lifetime and a lot of money to correct it. 2-minute brush and mouthwash in the AM, 2-minute brush and floss in the PM."
16. "Don’t wait until you have 'time' to start a fitness program. Because then when you get busy again, you’ll stop. The best time to start is actually when you’re busy. Learning how to fit it in when times are tough means you’ll stick with it over the long haul."
17. "When using text messages or IMs for business, say everything you need to say in the first message. Don’t just say 'hi' or 'hey' or 'are you there' or 'are you busy.'"
18. "Instead of feeling that you've blown the day and thinking, 'I'll get back on track tomorrow, think of each day as a set of four quarters:
• Morning• Midday• Afternoon• Evening
If you blow one quarter, you get back on track for the next quarter."
19. "Many problems in marriage are really just problems with being a bad roommate. Learn how to be a good roommate, and it will solve many of the main issues that plague marriages. This includes communicating about something bothering you before you get too angry."
20. "Ask yourself 'what does it matter to me' the next time you find yourself judging someone for their clothing or hobbies. The more you train yourself to not care about the personal preferences of other people, the more relaxed and nicer you become as a person."

Mom is totally humiliated after her kindergartner tells the teacher what she does for work
She was clearly mortified.
A mom is embarrassed by her child.
One of the great joys and stresses of parenting is that you never know what will come out of your child’s mouth. When you have young, inquisitive kids, they can say really inappropriate things to people without realizing they were being rude or possibly offensive. TikTok influencer Aurora McCausland (@auroramccausland), known for her DIY cleaning tips, recently told a funny story on the platform about how her son believes she makes a living. The problem was that she heard about it from her child's teacher.
Mom is embarrassed by her child
“The other day, I went and picked my five year old up from school and when I get to his classroom his teacher pulls me inside and says, ‘Hey, today he wanted to tell us about what Mommy does for work and said that Mommy makes videos in her bedroom but only when I'm [he’s] not at home,” McCausland recalled.
Given her body language while telling the story, McCausland was clearly mortified after hearing what her child said to his teacher. It makes it look like she may be posting videos to adult sites while her child is at school, which most people wouldn’t want their son’s teacher to know about.
The good news is that another teacher was there to clarify the young boy's comments by adding, “I think she makes TikTok videos.” The uncomfortable situation was a great invitation to chat with her son about what she does for a living. “So I have to have a conversation with my son about how he tells people what I do for work,” she finished her video.
The funny video went viral, earning over 1.7 million views on TikTok, and inspired many people to share the times when their children had funny ways of explaining their careers. The commenters were a great reminder to parents everywhere that if your child says something embarrassing, it's ok, just about everyone has been through it.
Moms share their most embarrassing moments
A lot of parents spoke up in the comments to show McCausland that she's not the only one to feel embarrassed in front of her child's teacher.
"My son told everyone that we were homeless (because we don’t own our home, we rent)," KBR wrote.
"I work in ortho.. my daughter told her teacher I steal people's knees bc she heard me talking to my husband about a knee replacement," Aingeal wrote.
"My son told a teacher we were living in our car over the summer. Camping. We went camping," Kera wrote.
"In kinder, my son thought Red Bull was alcohol and told his teacher I liked to have beer on the way to school," Ashley wrote.
My niece told her teacher her mom and dad work at the wh*re house. They work at the courthouse," Ellis wrote.
"My husband works as a table games dealer at a casino. Kindergartener, 'Daddy's a Dealer!' We now start every school year clearly stating he works at the casino," CMAC
"My son said we lived in a crack house…There’s a tiny chip in the wall from the doorknob," KNWerner wrote.
"My dad is a hospice chaplain and officiates a lot of funerals. My son and nephew were asked by their preschool teacher if their papa was retired or had a job. They told her his job was to kill people," Tiffyd wrote.
"My son said "my dad left me and I'm all alone" to a random person at the zoo. My husband was just at work," Shelby.
"I am now in my 70s. In my gradeschool, during the McCarthy era, I told my teacher my dad was a communist. He was an economist," Crackerbelly wrote.
"In Kindergarten, my daughter told her teacher that mommy drinks and drives all the time. Coffee. From Starbucks," Jessica wrote.
"Well I once told my kindergarden teacher a man climbs over our fence to visit my mom when her husband is not home... It was a handy man who came to fix gates when they were stuck," Annie wrote.
Ultimately, McCausland’s story is a fun reminder of how children see things through their own unique lens and, with total innocence, can say some of the funniest things. It’s also a great warning to parents everywhere: if you aren’t clear with your kids about what you do for a living, you may be setting yourself up for a very embarrassing misunderstanding. So, even if you think they know what you do ask them as see what they say, you could save yourself from a lot of embarrassment.
