It's just not funny when a person who hasn't seen you for months making fun of you.
It's not funny when you are not in the mood to be the butt of a joke and it's best to walk away from discomfort scene.
It's not funny anymore when this person insults you badly for not taking the joke.
But it's getting very funny when she continues barking at you and she says it was supposed to be a joke.

If you couldn't make people laugh at your joke, the reason is simple - it's not a joke and it's not funny. And if your joke is not funny but you make people feel miserable, all you need to do is to say a little word called 'sorry'. You don't attack people who don't get your joke. In a way, that also proves that you're sick in your head. You're just good at making fun of people.

Attacking people is not funny. But attacking people for misunderstanding a joke is very very funny. What you did say to insult people when you were angry, people remember.

After all, that meaningless life is a real joke. Pathetic. And disgusting.
