When David was younger, he spent a lot of Saturday nights on his knees: in alleys, in men’s rooms, occasionally behind a hedge in Central Park. He liked it rough and he still does, but he tries to be safer about his choice of partners and locations these days. He didn’t expect an attempted mugging to be the cause of his relapse. The guy shoves him up against a tree and puts a knife to his throat, and something in his voice makes David want to offer him anything – so he does. It was a stupid idea – David’s had a million of them – but he got it out of his system. When his mugger shows up at his door in the rain like a lost puppy, it’s hard to say who is more surprised when David invites him to come inside.
