A is playing restaurant. After bringing me my meal and dessert, she said "And now would you like something to refresh your mouth? Some kind of drink with mint in it?"

W out of the blue while we are in the car: We shouldn't drink our pee because it's really yucky.

Me: What??!!! That's right, but why did you say that? Did you try to drink your pee???!!

W: No. It's just yucky.
