People in my life are like ghosts passing though; repeating memories of different past experiences. I guess the value in it is to learn from the past though and make it better, with practice.
Even pets. Holding Booty this afternoon, watching tv, I suddenly remembered how my pet bunny, Bunny, used to feel when I held her. Same white paws. Same huffy breathing sometimes (similar name now that I think of it). Small, fragile bodies, but a burst of energy when tired of being held.
Of course Booty is now, Bunny was then. but it felt so sad all of a sudden to be holding something that was so similar to someone else years ago.
EDIT: But Booty's smarter than a rabbit.
