RIGHT after having a snack...
Ana: Mommy, can I have a snack?
Mama: No. You just had one.
Ana: But I'm hungry. Can I please have another one?
Mama: Because you can't just keep eating snacks all day long.
Ana: Why can't I eat snacks all day long?
Mama: Because if you eat constantly you'll get chubby.
Ana: But Mommy, I want to be chubby, just like you.
