The little things that rustle your jimmies

I hate, like many others here, people who walk slowly, especially in groups of two or more when they're walking next to one another taking up the whole sidewalk. The worst are what my mother calls "flying wedges," the horrible people at amusement parks like Six Flags/Disney World who have the 165 person strollers and somehow manage to take up the wider walkways there just by themselves.

I hate students that can't be bothered to even throw on a pair of jeans to go to class, no matter if it's a 12:00 PM lecture or a 7:45 PM lab. I know your sweats are comfortable, but you're paying roughly $100/class to go here, so dress like you care.

I'd list so many more (like racism, sexism, ignorant bros), but they're big things that rustle me, so perhaps not for this thread.
