Unchained Melody

Why a chain and a post, well it is easy. I must be as thick as a post, and chained up well. I went shopping with Mary my wife today, not unusual, but the usual outcome. The first time I went shopping with her, oh let's just say 40 years ago, we went into a shop, saw the perfect garment, but no, let's check a few others. Hours and hours later we rush into the first shop a few minutes before closing to buy the first item. This time of course we had to drive 30 mile round trip to one of the other shops.
