Toast

Breakfast at Grandma's on Sunday was replayed to me by Daddy upon his return Sunday evening.

Mary was sat after her cereal at the table patiently or otherwise waiting to go and play. She kept raising both hands up in the air, fingers up, palms towards the chest. "Toast"
Grandma asks what it is she is doing. Daddy informs her it is the sign for Toast.
Grandma says OK if she wants toast I shall go and makes some. She toddles off to the kitchen as dutiful Grandma's are want to do. Mary continues signing toast.

A few minutes later Grandma returns with desired item. And signs toast.

Mary looks at it agrees with Grandma, signs "Toast" and then leaves the table with a nod.

This is so Mary. Just checking if you would obey my command. And of course Grandma would.
