But what if I do?

In the car today, on the way home from swimming lessons, Roland proceeded to pester me.

"When do you think you might move me out to the country?"

Roland really wants to live on some acreage. 

"I don't know, Roland"

"Before I'm ten?"

"Maybe."

"What If I earn the money myself?  What if I discover the cure for cancer, and also the thing that scientists maybe don't know about?"

(He thinks he has figured out the real need for the uvula)

"Before you're ten?"  I inquire.

"Yeah."

"Okay then."
