Well if I woke up invisible I would haunt or "haunt" the people I hate. It would be awesome to be invisible but its impossible to make yourself invisible so, yeah. Another is I would kick or hit someone in school and the person behind them would get punched. I would be in school doing whatever I wanted. Also I would steal a phone from a store(Joking) and a couple pieces of candy and go to LA. However I would be sad because no one would see me.
I can't think of anything else. Sorry.
