Dropping the girl off at the end of the date, I had a long drive home and didn't want to go off-route to find a bathroom (I'm an expert at easily getting lost).
I smiled and said, "Thank you very much, I had a really good time! Um, is it OK if I use your bathroom?"
Her: You can use the driveway if you want.
...
Me: Are you serious?
Her: Sure, you don't have to park on the street, you can pull into the driveway!
