That's true bro. But I don't think it's because other people aren't interested in you or don't have time for new friends. I think it's because in these situations when you are the new kid to the social clique/workplace/club, the onus is on you to take initiative to make friends. Sure there are probably ass-holes but you probably don't want to bother with them anyways. But most people are friendly if you make the move, but they'll never know that you are interested in bromance/romance if you never do.

Hell, people in the club probably think you are the one with so many friends that you don't want to talk to them because you are just there for the hobby.
