Characters in stories often cling to the past. That's reasonable, because people do it in real life, too. Sometimes it's good, as shared history is what keeps some friends and couples together. Sometimes- not so good. When our grandchildren stayed with us four years ago, they were three and five. They accidentally left behind a plastic glow-in-the-dark dinosaur nightlight. When we called our son and asked if we should post it to the other end of this large country, he said they'd pick up another one.
So, there sits dino, faded white from his original purple. When our grandchildren come to visit later this year, will they fall on him with cries of joy? Will they remember him at all?
