This kind of person is annoying, self-righteous and completely inconsiderate of other people's feelings.
I can't stand it when I go back.
I can teach him a lesson. It's too timid to swallow it back, and the more I think about it, the more angry I am.
I don't feel ashamed, and I'm not afraid of ghosts knocking at the door in the middle of the night. Do the right thing, stand firm, not afraid of him.
