When someone's collar is twisted, or their hem is turned up, or their pant-leg is caught on their shoe and they're just walking around like that. I have this horrible need to *fix it*, though i don't on strangers. (Fair game if i know you.)

Smudged lenses on glasses. Clean them! I can't stand to look at people through big, smeary spots on their glasses.

People leaping in to say 'bless you' before you're even done sneezing. Don't do that. Just - stoppit. I never say it, nobody blesses you when you cough, just - keep it to yourself.
