Reason #3948894 that you know you are getting old:
You're taking your kids to their first rock concert.
So I was talking with my daughter (12) this evening and she says "hey Dad, do you like Motley Crue?"
I proceeded to tell her some of my Crue stories:
A dozen or so concerts, hanging with them backstage at Monsters of Rock '90 (maybe it was '91) dating Vince's cousin, hanging with Vince down in Portland when he was doing the PIG Racing thing, almost breaking Micks hand backstage in 99/00 (whatever year they toured with Anthrax and Megadeath) etc.
Needless to say, my kid though that was pretty cool!
She asks if we can go see them next weekend in Nashville (sold out) so we jump on eBay and bought 4 tickets for this coming Saturday.
In a way, im pretty stoked my kid is old enough to do fun stuff like that with her. But im pretty freaked out that im old enough to have kids interested in going to rock concerts!
