Cut Her Loose
Seymour says that Iz's nosepicking is driving him nuts. She does it compulsively, and thinks that if she does it with the other arm blocking her face then we can't tell what she's doing.
I told him to cut her loose! She is six, and he needs to tell her that if she wants to pick her nose in public then that is her choice. The first time one of her friends sees her doing it will be, I suspect, the last time. Then she'll learn to do it in secret like everyone else except me, because I never pick my nose.
