Inexplicable

Most of the time, I have a pretty good sense of what's going on with my kids. But every now and then, I'm mystified.

Such as after this conversation (the Papaya was perfectly happy right until this point - he was playing while I was cutting potatoes in the kitchen as a part of supper preparation):

Papaya: (whiney voice) - Don't eat the strawberry, Mommy!
Mommy: What? I don't have any strawberries. (There haven't been any strawberries in our house in weeks, although we did eat some two weeks ago in Flagstaff.)
Papaya: Mommy, don't eat the strawberry. Spit out the strawberry, Mommy. Spit it out!
Mommy: (Opening her mouth wide & showing Papaya.) My mouth is empty, Papaya. There's no strawberry in there. There are no strawberries in this house.
(Papaya walks away & starts to cry.)
Mommy: Why are you crying, Papaya?
Papaya: I lost my strawberries!

Note: Whenever the Papaya is unhappy for no specific reason, or at least no reason that he can articulate (for example, waking up too soon from a nap), he kind of whines/cries, and when asked why, says "I lost my pennies!" It looks like there may be a variation on that now.
