Lydia Logic

I've recently had the following two conversations with my youngest daughter:

"Lydia, when you whine and scream, nobody wants to be around you."
"Taylor (Lydia's little friend) does, she doesn't mind it when I whine and scream."

"Lydia, it's rude to ask the doctor for a sucker. If he offers, then you can take it, but it's rude to ask."
"Momma, if I say, 'MAY I PLEASE have a sucker,' it's o.k."

Lydia logic--it's taking every last brain cell in my head (and a lot of God's grace) to parent this child.
