On the way home from school, I found a bus ticket on the ground.

Me: Oh yeah! A free ride.

Iris: For two or just you?

Me: You’re always free. Where should we go?

Iris: I don’t know, where do you want to go?

Me: How about the taco bus?

Iris: Great!

(pause)

Iris: You know we’re not free on the taco bus, right?
