Yes or no?

Walter's best, most consistent form of communication is the head nod and shake. He's very good at answering yes or no questions. The hard part is figuring out which question needs asking. Which means many of our conversations go like this:

Me: Do you want milk?

Walter: Head shake

Me: Do you want strawberries?

Walter: Head shake

Me: Do you want fishies?

Walter: Head shake

Me: Do you want blueberries?

Walter: Head shake

Me: Do you want banana?

Walter: BIG NOD

SCORE! Banana it is!
