<human>: Can you give me a shortened version of the text?

My wife is taking some medicine to deal with her diabetes, and one of the side effects she's experiencing is moodiness.

She's heading over to her grandparents' house. It's cold and kinda rainy outside. I stepped outside in a t-shirt, immediately got cold, and turned around to go back inside to get a hoodie. As I turned, instead of saying 'fuck that shit', I said 'f that s'. She misheard me and thought I called her a fatass. She got really upset and wouldn't listen to me when I tried to explain what I actually said. Now she's driving there crying. I feel terrible even though I know she'll get over it once she's able to think more clearly.
<bot>: Wife thinks I called her a fatass. Think before you say something that might be misheard, especially if your SO is liable to refuse to listen to reason.
