A: James, eat your candy after dinner, please.
B: I just want to eat a little now.
A: You'll spoil your dinner!
B: My food won't rot if I eat a little candy.
A: What do you mean?
B: When food spoils, it goes bad. My food won't go bad.
A: It won't rot, but it won't taste the same, either.
B: Why won't it taste the same?
A: Well, if you eat the candy now, it will stay in your mouth.
B: I guess so. Why is that bad?
A: I don't think you want blueberry-flavored mashed potatoes!
B: You're right, I don't! I'll eat the candy later.
