I have a lot but here are a few:

When some people are mean but think it is funny. Like today, my friend and I were at a UIL event and there was some kid holding the door with his foot. When we walked in he let his foot go so the door hit us. He of course started laughing That has happened to me before and it really irks me.

When a guy and his girlfriend start kissing in public (not just a little kiss but like kissing to an innapropriate extent). While we were in San Antonio, we were waiting for a trolley and there was this young couple who decided it was o.k to be kissing not only on the lips but on the neck. Then the guy put his hand down her pants as to touch her butt. Gross all this while a mother and her young children were waiting for a trolley

just a few but i have many more...
