Sit cross-legged. I can do it for maybe 10 seconds max, but it's just so uncomfortable. Never was able to even as a kid. I think I'm just not flexible at all.

Shut the fuck up

even

Swim

Fold long sleeve buttoned shirts

recognize, remember, confront people. anything people.

Fall asleep.

Well, I guess it does technically eventually happen to me sometimes somehow. But not when it should.

Burp - I just can’t do it. Also whistle or roll my Rs

Diving. Thousands blown along multiple failed exams. Still get made fun of in my family and work due to that.

Eat bread (celiac). And riding a bike...

Keeping my systems (laptop, smartphone,...) properly maintained and functional (software-wise).

They are always just a barely functioning mess hanging on a last thread. Getting around bugs instead of finding fixes, ignoring non-critical errors, using 50 simpler tools instead of 1 more complicated one because it feels easier at first, holding off-of updates because it absolutely will break something in my stupid setup, doing something in a simpler stupider alternative way instead of doing it properly,...

Basically a software equivalent to old beaten up laptop you got for free that has broken plastic fixed with duct tape, few broken keys, half of the screen's backlight not working and charging connector holding on velcro.

Being social

Two things at once.

I can't snap very well. Or whistle

Remember where I put my keys and or wallet. Def didn't put them in the bowl my wife got for me by the door specifically to put those things in.
