So lately i have been visiting friends at colleges and from what i realized is that there are hundreds of girls walking around there dorm. My question is since i don't go to their college should i stop them and do a pace opener then an opinion or just go direct or situational. What do you think is the right opener for that type of situation.

As crazy as this sounds, it depends on the school you're visiting and your friends relationship there....

Ive found that some schools LOVE visitors and the people there will be intrigued in your being different, whereas others are exclusive and disinterested in outsiders....Without getting too specific, the best openers I use tend to DHV something unique about my doing something else with my life, other than being in there school...and it always draws crowds....

"Why do you guys always play beer-pong, that was cool as a high-schooler...(lead in)"

"Does anyone here know about...xyz...jeez, you guys are behind..."

These are kind of "negs" but it all works! Cheers Good luck!
