P is for Peanut Butter and PopPop

Monkey wanted some bread, and then decided she needed some peanut butter on it. So, as I'm getting the Pnut Butter out of the pantry, I ask her "Okay, but what letter does Peanut Butter start with?". I'm figuring that she'll tell me "A", like she usually does with words that she and I haven't "learned" yet.
Not so. Not only did Monkey inform me that Peanut Butter starts with "P", she then preceded to remind me that P is also for PopPop! And, then of course, she had to tell me that SueSue was a girl. Both things being true, of course. :-)
