A toddler kept tapping a woman's arm on a plane. Her response holds a lesson for us all.

Being locked in a metal box with 150 random people all hurtling through the air at 30,000 feet is quite the social experiment, but one many of us do willingly in this age of air travel. One of the most notable parts of that experiment is that you never know who's going to sit near you on an airplane. Will you get the quiet reader? The Chatty Cathy? The cougher who doesn't cover their mouth? The sweet-but-over-perfumed old lady? The parent with a baby who screams from takeoff to landing?

Flying can feel like a game of roulette, especially when you find yourself sitting near one of the most unpredictable forces on Earth—a toddler. Tiny tots might can for the most delightful trip ever or the most annoying one, but as one couple demonstrates, the difference sometimes comes down to our own attitude.

A video shared on Reddit reads, "We were on the plane when this baby's hand kept reaching out and touching my arm from behind…" At first, we see a zoomed in shot of a woman's next to the window as a little hand reaches around the side of her seat and taps her on the back of the arm, repeatedly and enthusiastically. Then the camera pants to the woman's face and the face of the man with her, and their expressions say it all.

Clearly, the child is enjoying the feel of the woman's skin on the back of her arm. Tap tap tap, rub rub, squeeze, tap tap. No hesitation, zero sense of decorum, just a totally oblivious toddler sensory experience. A little annoying? Probably. Pure and wholesome and worthy of a laugh? Absolutely.

This woman could have asked the parent to stop their child from touching her (and she may have eventually). Not everyone finds small children cute and some people have sensory issues of their own that make such encounters more bothersome than it would be for others. But assuming the toddler arm massage was temporary and that the parents saw what was happening and stopped it, the reaction of the couple is a perfect example of finding the joy in life and rolling with the punches.

As the post reads, "Those small hands are a sign of absolute tenderness," and people are loving the immediate mirthful reaction the pair had to the wee one's curious little fingers.

"Nothing cuter than seeing a baby flailing their arms and slapping things because they are happy. They have no control. They just know they’re happy."

'The baby slaps 'yep this is good arm' tap tap."

"My grandma had the softest bat wings in the world. I used to love to touch them. I’m sure she was self conscious about it but I loved them lol."

"As a parent I would be horrified to discover my kid was doing this but so relieved that they were such good sports about it. These are the types of people we need on airplanes."

"Same, I’m always concerned how my kid behaves on a plane ride (and he freaking loves being on a plane) but I find most people to be such good sports around him. Love when it works out that way. Though I 10/10 would have snatched that hand away soon as I noticed 😂😂😂."

"The people laughing were so kind! I can imagine some people would lose it if a child did this but they just enjoyed it. 🥰"

"Seriously! Seeing the humor in everyday life says a lot about their temperament. They seem like great folks."

Some people shared their own stories of toddlers similarly pawing at perfect strangers. It's helpful to remember that these little ones have only been on the planet for a hot minute and they barely have anything figured out yet. The nuances of what and whom to touch and not to touch takes a while, as does having the impulse control to not just reach out and feel whatever looks soft or interesting in the moment.

"Oh my gosh, that reminded me of a time when my son was small, maybe 18 months? We were in line at a restaurant and he was toddling around my legs and holding on to my finger while I chatted with my sister and mom. I felt him let go, and looked down to see where he was off to. He was standing by a lady a couple of people ahead of me who was wearing fishnet tights. He was rubbing her leg with his tiny baby hands and looked just MESMERIZED. I, on the other hand, was absolutely mortified and grabbed him up, apologizing all over the place, but luckily she was very cool about it and was just laughing.

Little kids like to just touch stuff to learn more about the world around them, but parents need to be constantly paying attention so their kid doesn't accidentally harass someone!"

"A little kid of around that age did this to me at restaurant once- he walked up to me, rubbed my bare forearm, and then gave me that same mesmerized look and tapped me with his hand a couple times. I didn't think too much of it (was more puzzled/confused than anything), but his mom had to pick him up and apologized anyway. Kids are funny haha."

"Yes this is so adorable. The last time I took a flight with a kid sitting behind me he was kicking my seat for like two hours before I politely turned around and gave a look to his mother and said 'hey my little friend. I know this flight is long and you wanna get out of this seat but do you mind not kicking my seat anymore?' Then I gave him a piece of paper and some (like 5 out of my 50) colored pencils and asked him if he could make me a secret drawing and pass it to me quietly and I’d make him one. I’m an artist and I always carry watercolors and colored pencils and sketch books on flights. We ended up passing drawing back and forth for the rest of the remaining 5 hour flight. He didn’t kick my seat again… I suspect it was the poignant look I gave mom. But so he was engaged. Every 20 minutes or so I’d feel a little tap on my arm and a folded up little drawing would appear. I still have them in the pocket of a moleskin somewhere."

Here's to grownups joyfully embracing the reality of co-existing with small children, in all their curious, sensory-driven, hands-on glory.
