the mother assured her, turning to her middle daughter.
“Now why were you laughing?” she asked.
“You always said if it tickled, I could laugh,” she answered.
“True enough, honey.” The mother smiled, remembering her newlywed days.
“Now it’s your turn, baby,” she said turning to her youngest daughter.
“Why was it so quiet in your room last night?”
“Mom, don’t you remember? You always told me never to talk with my mouth full.”
