--You knew all the Djs now currently in your scene before they had ever touched a record. (not really a jaded thing, more of a "i've been around too long" thing ... which is kind of hand in hand...... )
--You are humiliated by any pictures of you wearing candy anything, and have ever said "I was really stupid back then"
--Your 'best friends' now have regular names (chuck, mike, laura) instead of raver names (LyndsEy, FirEball, SmilEy) and you NEVER want to go back to the raver names.
--You stop doing ecstasy and starting doing various types of speed (leagal and illegal) so you can "party sober" and "not look fucked up and grose".
--you stop initiating conversations with random people
--You always stand in front of the crowd while the dj spins (who is your close friend), not dancing, nodding your head to the music, resisting the urge to attack the person who just sprayed water all over the front of the crowd consequently spraying your glasses making it impossible for you to see through them. This is annoying now because they were already greasy from the air and wiping them off will only spread this grease and funk and now you have to go the rest of the night without them on and you don't have good vision to start with and you REALLY REALLY want to attack that person... really really.
... ok this last one was just me but i think it *could* be universal.
