My son, Dylan, was in a school play in the 6th grade, and I still remember a conversation I had with one of the other moms. She told me her son wasn't chosen for an acting part. His only job was to open the curtain, so she didn't plan on going to the play.
I told her I thought he had a pretty important role, because if the curtain wasn't opened, no one would be able to see the play. She thought that was a strange thing to say, but I really meant it.
