I've been to big parties like that, and you're right. I just think some girls are too scared to go because there are so many guys. I'll be the guy sitting in the quieter room smoking and drinking with my buddies. I prefer small gatherings of friends, which usually cosists of an even ration of guys and gals.
I don't keep many friends, I can count the amount of friends I have on 1 hand, really. Too many fake people out there, I don't want to deal with them in any capacity where they can take advantage of my trust.
All my friends are 100% true though, you can't ask for better (except maybe Aaron's musical tastes).
