This story came to me from a friend in America.A little girl was traveling with her family on one of those long sleeper trains.When night came she was put in the upper bed and told that God would look after her.As everyone began to sleep,the little girl got a bit frightened,and called out,"Mummy,are you there?"
"Yes,dear,"answered Mother.A little later she called,"Dad,are you there?" "Yes,dear,"came the father's voice.
This was done several times.Until at last another passenger got unhappy and said,"We are all here!Your father,your mother,your brother and sisters.NOW GO TO SLEEP!"
It was quiet for several minutes,and then the child was heard to whisper,"Mother was God?"
