Not really. I apologize, I can't follow that thought. But, thank you for writing that, I appreciate it. I tend to think of my daughter having won the relay race last spring as pretty much set in stone and an immutable event. The trophy on her shelf is testimony to it. In fact, my daughter herself is testimony of an event about 14 years ago, that did in fact occur on a certain day.
If the past were mutable, then many parents would probably have gotten rid of some of their kids long ago. Not me though.
