Most Helpful Guy
Average looking depends on who you ask. I've had girls that I thought were drop-dead gorgeous, while my friends, looking at the exact same woman, couldn't find the attraction with a map and a Sherpa guide. Inversely, I've seen my friends drool over girls while my only thought about her was "meh".
Like others have said, if there's a guy you like who happens to sit near you, say hi! Give him some kind of opening to talk to you. Who knows where it could lead?
