Masking.

Riding a bike

I learned to tie my shoelaces!

Not really much else, I fear... I quit playing music almost entirely, which was a pretty big part of my life as a youngster.

I learned how to fixand build things with my dad and grandpa. Now I'm a mechanical engineer and use those same principals I learned from them 30 years ago.

Got my first skateboard 41 years ago, am as excited as I've ever been that I get to go skating today.

Walking as quietly as possible around the house.

Reading

When I was nine another kid taught me how to make this really cool paper airplane that looks more like a shuttle than an airplane and flies pretty well too. I still make them when I’m bored, and when my kid is old enough I’ll teach him too.

reciting pi to this many digits from memory any chance I get:

I can usually tell by someone's gait and posture whether or not they're likely to try to hit someone in the next hour or so. If it seems likely I offer them drugs. Usually by the time my coworkers are able to tell it's too late to offer.

Peeing in the potty

Whistle with my fingers, took a good few weeks of practice over one summer blowing spit all over my fingers but eventually I learned. Still a really useful skill today.

I can swallow air and belch on command. Maybe I should list it as one of my skills on my resume

Writing cursive. But after seeing my coworkers I could just say writing, there's this kid in particular that he barely knows how to hold a pen. And I'm supposed to be the one without an education.

I can roll a coin or a pencil through my fingers. Do this mostly in boring meetings.

Wiggling my nostrils

Lying

I can wiggle my ears and nose.

Being able to play multiple different musical instruments.

I have a loose scalp, I can make it appear as if I'm wearing a wig.

Sing.

Singing 🎵

I learned by exploring my mouth with my tongue that I could clean out my nose from the inside.
