Onion Breath

While halfway done with his "take out dinner" burrito...
Brother - "This burrito has onions on it."
Mommy - "You like onions."
Brother - "No I don't."
Mommy - "Do you like the burrito?"
Brother - "Yes, it is good."
Mommy - "I think that you just don't like onions on your hamburgers."
(Bad, I know...)
Brother - while looking at his burrito quizzingly, "Oh."
