You're expertise of said parties is remarkable, did you have a cover charge to pay for the booze and weed, or was it BYO?AN UNSUPERVISED PARTY....a kid's parents are gone and stupid enough to leave the kid alone. He throws a party...word gets around and tons of kids go to the party whether they know the person or not....they want to party. It's what they do. Boys AND girls, unfortunately. Do you think they have invitations engraved ahead of time and when they get the RSVP's they see how much booze they need? LOLOL We're not talking about a 2nd grade party...probably the last one you attended.
