Early one morning, a father was awakened by the smoke detector in his basement.  He woke his wife and they quickly went to their children's bedroom and woke them up and started heading for the door through the smoke which was getting quite heavy.  The father was carrying his one and a half year-old daughter in one arm and held the hand of his four year-old son with the other.  The son, being scared and unsure of what was happening pulled his hand from his father's clasp and ran to what he thought was a place of safety -- a corner of his bedroom where his favorite stuffed toys were kept.  The father got outside and called to his son who appeared at the bedroom window crying and calling for help.  The father called to him and told him to jump, but the boy yelled in reply, "But I can't see you!"  Then the father called back with a reassuring message:  "That's alright, I can see you!"
