Home for the holidays

It's the morning after Thanksgiving and I've stayed the night at my Mom and Dad's. The family has plans to go out to breakfast at a popular restaurant. We're in the kitchen.

Mom: You want something to eat? Cereal, English muffin, toast, juice? Our reservation isn't for two hours yet.

(I pour a bowl of cereal. I'm about to pour the milk.)

Mom: You don't want to eat too much before breakfast.
