Message of Sisterly Love

A large chalkboard hangs in our kitchen. It holds the kids' chore chart as well as reminders and important messages to one another.  I might put dinner instructions up there on a night I am at work, or a note to turn in a paper for school, or an item to be fetched at the grocery.

Some of us apparently use this chalkboard to make rude faces at our sister.  I used the process of elimination to figure this out.
