My housemate, Jane, is a wonderful artist and has this strange idea that everyone around her is some sort of artist, too.  She hung up a large piece of paper in our kitchen and insists that visitors add something.  I showed it to my brother who is staying with us this week:

Me: I added the elephant.

My brother: What elephant?

Me: THIS elephant.

My brother: Oh.  I thought that was a spaceship.
