I could go on on a few different topics because my day is pretty much composed of me hating everything that happens around me, but instead since I don't want to spend all night here I'll list a few stranger ones.
I really hate fake-orange light in the city during the night, and generally hate the night unless it's somewhere away from any civilization.
I despise people who walk slowly and block me in narrow corridors or groups that do that on the street.
I cannot stand when something falls down. As in, off a desk. It can be the most irrelevant thing in the world, let's say the complete and categorized works of Westboro Baptist Church, and I'll still have to pick it up, for some reason.
I want to murder people who make loud noises or having complicated conversation while in a public bathroom, and especially people who hang around such bathrooms, because It's just such a lovely place to be in.
And pretty much most of the things listed in this fine thread.
