I said it above, too, but I hate it when people can't pick up after themselves. It's weird because my family is generally pretty messy, but it didn't catch on with me, I hate it when people leave their stuff around. I do it, but I swear not as much as other people lol
When people type 'should of' instead of 'should have.' Ugh.
And of course girls who say they are fat when they AREN'T. This will sound conceited, but I also hate when people talk about how thin I am like it's something I have complete control over. Just the body type and metabolism I inherited from my parents, thanks.
