How should I get revenge?!?

i've gotten actual revenge on an ex- i messed up stuff, and it makes you feel worse. the best thing to do is be really happy and act like nothing at all happened, hang out with some guys, try to look awesome and be really sweet. it will honestly screw with his head - act like he meant nothing to you, its not worth getting in trouble at school, if you really want revenge try to get it outside of school.
