If you'd known he was gay, you wouldn't have pulled out your tits and frightened the poor boy away. But it was too late for all that now, and the two of your are pegged into amateurish silence.
You walk him awkwardly back to his apartment -- no, his boyfriend's apartment. He's far too paranoid to wander the tenth floor alone, and you don't mind walking him back to 1006. You watch him disappear behind the locks, and turn back.
Maybe you should have put it together sooner, but you can't feel too bad. Sexuality is a difficult thing to diagnose. You light a cigarette, smiling with the knowledge that nobody even knows that the man in 1006 is gay. Shit, wouldn't that be a bombshell?
