If i were a ghost i would dress up all dapper the suit and tie with a top hat and all that, then i would go about my daily life as was, watching anime and going to school to learn and all that but for free now and then i would mess with people of course, i would just troll people with a bunch of little things like prank calls from inside the house and anything else i could think of just to have a good time
And then of course i would hang around with all you other ghosts and just have a giant party
