Fairy Tales

A child asks his mother, "Do all fairy tales begin with, 'Once upon a time?'" His mother answers, "No, dear. Once in a while they begin with 'I'll be working late at the office tonight.'" "Does Daddy tell you fairy tales like that ?" "He used to." "What made him stop ?" "One day he told me he'd be working late, and I said, 'Can I depend on that ?'"
