No, I don't mean to start a My Hero Academia RP!
I mean personal quirks that are interesting, strange or otherwise noteworthy.
I'll name one of mine: I like sorting things. For any given thing I will create an internal sorting system in my mind and abide by it. For example, appliance remotes: I'll elect a place to leave them at and always make sure they are there when not in use, and properly sorted in some way. In my particular case, I sort by remote control height - the shorter ones on the left, the taller ones on the right in increasing order.
As you can imagine, this (and cases like it) are the source of some internal suffering and frustration for me as most people in my household do not value keeping things organized and in their due places nearly as much as I do, but on the other hand, reiterating my system does make me feel like there is at least some order in the maelstrom of chaos.
So what about you guys? anything you'd like to share?
