Julia: Mom, do plums have seeds?
Me: No, they have a pit.
Julia: What's a pint? (rhymes with splint)
Me: No - a PIT.
Julia: What's a TIT?
Me: A PIT!
Julia: What's a PIT?
Me: The hard thing in the center of your plum. It's like one big giant seed instead of a lot of little ones like blueberries have.
(she continues to eat, I continue to type)
Julia: I found the pit! It IS like one big seed!
