I think I see. Envisioning those scenarios may have a bit of satisfaction in them but ultimately I don't think they are good for you. In a way it sounds kind of like reliving something in your past. I'm not sure if you're envisioning having a response that makes the event turn out differently or not but either way I can't see it being a good way to spend time. There's no changing the past. The best thing you can do is to try to avoid those people as much as possible. Making fun of someone or bullying someone is just bad behavior. It reflects their bad character, not anything about you. They do this because of their own low self esteem. I guess in a way they try to transfer it to you or it just makes them feel better by hurting someone. I don't really understand the mind of a bully or a jerk that well.
