What actions or things upset you?

This morning someone cut me off from the right, getting between my car and the car in front of me, where he did not have enough room, so he had to slam on the brakes. If I didn’t slam on the brakes, I would have hit him. It made me really mad. I don’t usually get mad at things, but this really pissed me off.

I also get mad when someone parks in my spot at work. We have assigned spots and the alternative is parking on the street and dealing with meters, so when someone’s in my spot it can be very inconvenient (plus I hate that someone is there that should be on the street themselves).

I am normally pretty mild mannered and I want to know what things or actions really upset others on Fluther.
