It was the last day of school, and there was a rock band and all of a sudden, i started to head bang very fast and some people actually told me to stand up and do it, which actually lasted for a few seconds. It was also the last act there in which i had to be careful stepping down the stairs. I didn't realize almost everyone there looked at me until some one told me that because i was busy head banging and doing the metal horns.

tl;dr: I head banged during the talent show and everyone looked at me.
