My brother-in-law will go on like this with a story that seems like it's going somewhere, but then the stories never reach any meaningful conclusion. I'm not saying he keeps talking indefinitely, I'm saying he'll finish the story and there will have been no point. There's no big climax, there's no exciting or interesting conclusion at the end, he just tells you about some random, uninteresting part of his life as if it were a cool story to tell. He's the only person I've ever met who does this. It's really odd, and even after 20 years idk how to respond when he finishes.
