Kid Logic

The Scene:

The family is gathered in the kitchen.  Dad is scooping ice cream and passing a bowl to each child.  Once everyone is settled in with their bowl and spoon, Mom decides this would be a good time to sneak off to the bathroom.  After all, everyone is in the kitchen eating ice cream.  Surely no one will have a reason to follow her.

Mom shuts, but doesn't lock the bathroom door because, again, everyone is in the kitchen eating ice cream.  30 seconds tick by, and ten little toes appear beneath the crack of the bathroom door.  The handle turns, and a small face pokes into the bathroom.

MATTHEW:  Mom, I want more ice cream!

ME:  Matthew, for heaven's sake, I'm going to the bathroom.

MATTHEW:  But I want more ice cream!

ME:  Matthew, your dad is IN THE KITCHEN with the ICE CREAM.  If you want more, go ask him.

MATTHEW:  Oh.  Okay.

For the life of me, I cannot understand this.  Yes, Matthew has the most active Search and Bother radar of all my children, but still, how does this thought process work?  Let's see, Dad is standing in the kitchen with the ice cream... I think I'll go find Mom in the bathroom and ask her to get me some more...

Huh?

If nothing else, you'd think that by now he would have figured out that Dad is ten times more likely than Mom is to scoop out second helpings of ice cream...
