What have I made?

Anthony was playing with Legos (or Duplos if you want to get technical about it) and announced he was going to make a tunnel. A minute later he looked at what he had made and said it wasn't a tunnel; it was a hospital. I bet you didn't realize how many hospitals have accidentally been made by people who forgot to leave a gap in their tunnel and bridge construction projects.

A few weeks ago I started telling you about the audience for something I'm working on. I'm still not sure. What have I made? A YA novel or MG or just a regular novel? I guess we'll see when I'm "done."

By the way, Anthony eventually made a successful tunnel.
