Long stories with little, to no, payoff.
You know when someone tells you a story and keeps veering off to give details or exceptions that ultimately have nothing to do with the "punchline"?
For example, You-"Did I ever tell you about the hilarious time at Canada's Wonderland?" Me-"No, please tell me." You-"So we went on a Tuesday, wait it was a Wednesday - the 17th of July... Wait August? No, July... July 14 - oh ya. So, anyway we get there and John brought his sunglasses, no wait, he didn't... Oh that was the time at Cape Cod... Anyway - long story short: a bird crapped on him."
Ya, so that LONG story wasn't SHORT at all. So, Mr. Kipling, let's stick to bullet points! I'll ask for more detail if I feel that it's necessary and, guess what, I won't.
Long, pointless stories Suck!
