Put it into a real world context. Urban is often compared to a pub, so lets place it there.
Imagine you are in a pub, chatting to some people about something you are mildly interested in. You have a little joke with somebody, maybe you cross the line a bit as can sometimes happen with jokes. You just act the way you would with your friends.
Then imagine that for weeks after that, that person followed you around giving you shit. He gets banned from the pub, then returns, and carries on giving you shit.
Now tell me, what would you do? What is the right thing?
