history: I drove by a treehouse off the side of the road this morning. It made me stop and remember my treehouse from childhood. It kind of brought me down a little bit, I got really down this morning. I saw a treehouse on the side of the road and it made me remember mine. What happened to yours?
current: I outgrew it. It was a long long time ago back in my childhood.
next: That is a real shame, at least you can hold on to your memories.
