Doing something after I expliecetly request a person not to. An example is my boyfriend in college thought he was being funny, but he was actually being more annoying. Since I wasn't amused, he called me 'mopey' repeatidly which really rubbed me the wrong way. I told him that I didn't appreciate being called 'mopey'. He said, "well you are mopey". I walked out of the room.
When somebody says something they know is offensive to somebody else, then saying sorry before the other person can react so they can 'get away' with the statement. The person who I am thinking of apologizes not because he is sorry, but to diffuse the peson getting angry because he does the same thing often and seems to laugh at his own jokes.
Anybody who treats me like I'm stupid. I remember when I was about 9, my bro, sis, and I got our photo taken with Santa. When we got it back I didn't like the way my hair looked and mentioned that to my mom. The woman who gave the picture back pretended to fluff up my hair on the picture, gave a condescending smile and asked "is that better?". I may have been a kid, but I wasn't stupid.
