Why do teens like to party so much?

I never understood the party scene. My idea of great fun was to go camping in the mountains with several friends and play airsoft in the middle of the night. It starts with a campfire and roasting marshmallows and having a good time. Then, we'd split into two groups for the airsoft game on top of a lonely mountain around 1 A.M. This mountain top was just barely lit by the light of the moon. 

There was a small section of woods we nicknamed "terror forest" because someone would camp inside these woods and scream blood curling screams right before they shot someone. That someone was me, of course. Ahh, the girlish screams of those guys were music to my ears. Good luck my friend.
