All the Way at the Top

My children talk in their sleep. I know I have at times as well. It's not multiple sentences or paragraphs. Random words or phrases. 9 times out of 10, I can't understand a thing they are saying. Tonight, Brodie and I are working late (it's 11:24) and Alex and Joey fell asleep on the couch. Just a few minutes ago, Joey says, "All the way at the top" as clear as day and we imagine what he's talking about. Brodie wanted to start talking to him to see if he would talk back but he refrained. I'm guessing it had to do with trains. His life seems to revolve around them. A few minutes later he mumbles something that was unrecognizable. It made us smile. I love my children.
