I'm an idiot

I got drunk and told my sober friend that I would buy her dinner if she drove me home. I was very far away from my house and just had to go home, even though I had a perfectly good place to sleep that night, and a ride home in the morning. But no, I insisted on being in my own bed. And naturally on the drive home I told my friend an excessive amount of times to remind me of the promise I had made her. So what am I doing this evening? Taking my friend out to dinner. Lucky me.
