quirks

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...

What are some of your pet peeves? Me? I can't stand it when a song starts on mono, because it immediately makes me think that my crappy headphones have just started failing, which is yet another thing I can't tolerate.
