To give a better frame of reference to the "Not" at the end of yesterday's wordless wednesday, please listen in on a common conversation at our house as we are getting ready for quiet time:
Mommy: Jonah, do you want to pick out some books for quiet time?
Jonah: Yes, mom
Mommy: Which ones do you want?
Jonah: I want this one, and this one and this one (I reach for all the books as he points to them), not mom.
Mommy: You don't want this one?
Jonah: I want this one, not mom.
Mommy: Okay, just tell me the ones you do want, not the ones you don't want.
Jonah: Okay mom, I want this one. And I want the train one, not mom.
