Why should it bother you what view the puplic has of you? If I was in your situation, I'd alienate myself even more by running around the neighbourhood in a super hero outfit, to prove how childish I REALLY was.
But then again, I've went to school non unform day in boxers.
So it's best you do the OPPOSITE of what I've said. Which is NOT run around in super hero costumes, if my calculations are correct.
