How do you get someone back for doing something to you?

You mean you want revenge on somebody? Nice! I would give you many ideas for that and you to pick the best, but I don't know how bad the thing was. Tip: do something that is possible for you to do, and that is more less as bad as what the person did to you. You don't want to kill him/her (you could go to jail). Make sure the person won't have a successful revenge back on you. the best revenges involve embarrassment.
