I don't even remember the joke, I can take jokes perfectly fine. This is a sad outcome of something perfectly innocent.

I'll take it as a compliment that Louis never explained anything to me

edit: just to make it clear, I have no idea what joke it was, probably a funny one. I have no idea who took offence, and who caused any trouble. I just learned now it was because of a joke against me, but I had absolutily nothing to do with it.
