Dear Thomas,
Today we played an exciting game of chase. I started crawling around in your bedroom, and you loved it and started laughing. So, off I went crawling through the house and you stayed right on my tail. You laughed, crawling as fast as you could crawl. When we turned the corner to the living room, I hid behind the couch and jumped out at you. You jumped a foot and laughed. This has to be the best age yet!
