Input: Text: for my 5th or 6th birthday my parents took me to green day's american idiot album release party with tickets they won on the radio. green day had been my favorite band since i was a toddler, i knew every song.

on to the day of the show:

all dressed up with my head shaved into a mohawk, wearing a home made green day shirt. 2 guys that worked for the radio station sponsoring the event saw me, and thought that i was a rad dude or something and proceeded to invite me to get on stage while they were playing. i was excited beyond belief.
next thing i know i was backstage about to run on and jump around with green day, until i saw the crowd. there was probably not much over a thousand people. i then proceeded to get scared and start crying and ran to my mom

i hate myself for that more and more by the day
