I was walking through the home furnishing department of a store at the local mall, when I spotted the most beautiful rocking chair I have ever seen.  Its oak finish shone and the detailed carving on the back was very intricate.  I knew at first sight this had to be the chair where I would rock to sleep my first born grandchild.  None of my children are parents-to-be yet, but I knew in my heart I had to buy this rocking chair.  A salesclerk saw me looking at the chair and came over to assist me.  Just my luck, the price of the chair was reduced as part of a year end clearance sale.  I paid for the chair and made arrangements to have it delivered the next day.  When I arrived home there was a message on the answering machine from my daughter in California.  I returned her call and she announced that she was pregnant.  That is why I was supposed to buy the rocking chair.
