I'm more or less with eluuzion on this.
Just dress as you would dress; don't bother changing for him and his girlfriend. If he asks, answer his questions honestly. If he doesn't ask and stops showing up, then you know he wasn't really a friend to begin with.
And, since this isn't high-school, if he harasses you about your CDing, just call the ol' Five-Oh.
So you are aware, this advice was given to me by my good friend Jose Cuervo. Take it as you will.
Another sunrise anyone?
