You guess you could humour him for a while. Even if he is a rude arsehole, he could still potentially be vaguely more interesting than talking to yourself. Goodness knows you've gotten a lot of practise at that-- sometimes you even reply to yourself, just for shits and giggles.

Monologues are always good. And... Were you supposed to be doing something? You were, weren't you?
