While Mojo maintains an exquisite lack of interest in all things that are letters or numbers, Cookie forges ahead in trying to figure out they're used. We were reviewing several letters recently to try to think of words that use them. We talked about "B" and Cookie knew bumble-bee and banana. This got him thinking further:

"Do all yellow things start with 'B'?"

I pointed out some of the many exceptions to such a rule: lemon, jaundice, Botswana, and uranium ore. So now he's working on a new theory... something about the velocity of objects thrown laterally (at one's brother) while diving off the top bunk into a pile of stuffed animals.
