You ever make a joke and someone laughs and then apologizes like they weren't supposed to laugh?

Do some people not understand how jokes work?

Yep. Beware of long after the fact disclaimers like "... was laughing at you, incredulously, not with you..."

Yes but they were self depriciative subject matter maybe over the top too

Nah my friends usually have no issue laughing at dark humor etc

Can`t say that I have.

Only for a fake laugh
