Laura: Ralph, would you stand in the corner, please?
Ralph: Me? What did I do?
Laura: You were pulling Willie's hair. We don't do that here.
Ralph: I wasn't!
Laura: Ralph, have you ever heard of peripheral vision?
Laura: Well, I have it. It means that I can see out of the corner of my eye, and I saw you pull Willie's hair. Now, do you want to sit there and argue about it, or do you want to stand in the corner and get it over with?
