Thunderstorm

One summer evening during a violent thunderstorm a mother was tucking her son into bed. She was about to turn off the light when he asked with a tremor in his voice, "Mommy, will you sleep with me tonight?". The mother smiled and gave him a reassuring hug. "I can't dear" she said. "I have to sleep in Daddy's room". A long silence was broken at last by his shaky little voice: "The big sissy".
