Two women were in a hair salon talking about their home lives when the subject of flighty husbands came up. "It's unbelievable," one woman said. "I can never figure out where he goes at night." "I know exactly what you mean," said the other woman. "One second he's in the house, and the next he's gone without a trace." "Well," says a woman eavesdropping nearby. "I always know where my husband is." "How do you manage that?" the other two women asked. "Easy," she replies. "I'm a widow."
