My Brothers Sister

I was at my friends house and we were bragging about how little we can eat. My friend J.B sister said some times I don't eat all day. I asked her, "oh you fast?" Then she says, "No, I'm actually pretty slow." Then her mom told her fasting is not eating for a long time. That is why breakfast is called breakfast, to break your fast and eat. Then his sister goes, "How do you know?" I busted a gut so bad. She should have been a blond.
