They get what they want

Connor really wanted a Transformer Deceptacon and saw a way to his heart's desire in Gong Gong's wallet. All he had to do was convince his grandfather to take him to the store. The following conversation ensued:
C: Gong gong! Can you buy me a Deceptacon?
G: Hmmm, I'll have to go look around for one this weekend, and I'll bring it Sunday.
C: You can buy them anywhere. They have lots and lots of them at Target, Walmart, Toys R Us...I can show you. Can you take me tomorrow?
G: Tomorrow won't work because I have to take Po Po to a doctor's appointment.
(Connor flips through a Transformers catalogue in disappointed silence, then perks up)
C: Can Po Po drive herself to the doctor's appointment?
G: Well, Po Po doesn't drive well alone.
(Quiet again for a moment in deep thought, he suddenly turns to me with a revelation)
C: Mommy! YOU take Po Po to the doctor's appointment!
There was no resisting the perseverance of a 6-year-old. Needless to say, Connor got his Deceptacon with Gong Gong the very next day.
