...and everyone is there. But some people don't like the party. Maybe they don't have any friends there, they don't like the music, or what have you. So they decide to leave early. And everyone's like, "Man, why would you want to leave? This party is so awesome." And they're like, "Naw, this party sucks, and I think I'm going to just go." And they leave and everyone else just hangs around talking about how they miss the people that left, until at ten in morning someone tells them to go home.
And that's my metaphor for suicide.
