When she went past her oldest daughter's room she heard screaming. Then she went to her second daughters room and she heard laughing. Then she went to her youngest daughter's room and she couldn't hear anything.
The next morning when the men left the mother asked her oldest daughter, "Why were you screaming last night?" The daughter replied "Mom you always told me if something hurt I should scream."
"That's true." She looked at her second daughter. "Why were you laughing so much last night?"
The daughter replied "Mom you always said that if something tickled you should laugh."
"That's also true." Then the mother looked at her youngest daughter. "Why was it so quiet in your room last night?"
The youngest daughter replied "Mom you always told me I should never talk with my mouth full."
