One night a wife found her husband standing over their baby's crib. Silently she watched him. As he stood looking down at the sleeping infant, she saw on his face a mixture of emotions: disbelief, doubt, delight, amazement, enchantment, scepticism. Touched by this unusual display and the deep emotions it aroused, with eyes glistening she slipped her arm around her husband. "A penny for your thoughts," she said. "It's amazing!" he replied. "I just can't see how anybody can make a crib like that for only $46.50."
