Depends who you are seeing.
mylie cyrus, justin bieber -- it is probably best you keep that embarrassment at home. Unless you are there to creep on the girls and their moms.
Rolling Stones, Aerosmith, WuTang Clan and shit like that, get your old balls there and get down.
i guess the rule is if you are old enough to be a parent of the person you wanna see in concert you should just stay home and watch it online or something.
