Little six year old Sarah Federman, came home from school whining, "Mommy, I've got a stomach ache." "That's because your stomach is empty," her mother replied. "You'd feel better if you had something in it." She gave Sarah a snack and, sure enough, Sarah felt better right away. That afternoon, Shloimy, the family’s handyman, dropped by. While he was chatting with Mrs. Federman, he mentioned he'd had a bad headache all day long. Sarah perked up. "That's because it's empty," she said. "You'd feel better if you had something in it. My Mommy taught me that."
