When I’m the one interrupting someone’s joke, here’s what I’m thinking: “Hey! I know the punchline to this joke! Which means I know the same cool thing that this cool person knows! If I jump in with the punchline, this cool person will realize that I am cool, too, and we’ll become super best friends.”
When my joke’s being interrupted, here’s what I’m thinking: “Bitch, I don’t care if you know the punchline to this joke; I started telling it and so I deserve to finish it. How dare you steal my glory?”
And no matter which one I am in a given situation, I always, always forget what it’s like to be on the other side.
