Two sisters came home from school crying their hearts out. "What’s wrong?" asked their mother. The first sister started wailing, "The kids at school make fun of my big feet." "There, there," soothed the mother. "Your feet aren’t that big." She turned to the second sister and asked, "Now why are you crying?" "Because I’ve been invited to a ski party and I can’t find my skis." "That’s okay," said the mother, "you can borrow your sister’s shoes."
