you try and talk to Dave, one of the jocks, who obviously is a little ashamed to be here, as if his girlfriend knew, well lets just say he'd be sleeping in the toliet "Hey, dude, whats up?" You ask him "Nothing, nothing is going on, alright?" Knowing Dave, you try one more time before giving up "Dave, whatever is wrong is nothing to be ashamed of, alright?" Dave doesn't respond and instead starts tapping his foot impatiently.
You do have two other people you could try and talk to, or you could move on.
