DH and DD are at MIL's house already, I'm joining them tomorrow. The original plan was that I would get a rental car in Philly and drive to MIL's. Then we'd all load up and head west a couple of hours to join more family for Thanksgiving.
MIL is now terrified of the whopping 3" of snow she's expecting, so she wanted to leave their house at 7am tomorrow morning. That would have left me to fend for myself in the rental car from Philly. When she found out they're waiting for me she got all worked up. And won't stop talking about it. I swear, she has nothing else to talk about, so 3" of snow will dominate the conversation. DH is convinced that MIL will intentionally stay up all night Wednesday worrying about the weather, and will get us up at 6am Thursday to hit the road.
I am going to laugh my ass off if she only gets a dusting.
ETA: In other news, DH took out DD, MIL, and GMIL, and said it was like wrangling 3 toddlers. He said MIL didn't like how much (little) DD was eating, so she shoved a piece of pizza in her face.
