Can't argue with this logic

Little Sister has an interesting way of coming to conclusions.
This morning she asked me if she could watch "Little Einsteins". I don't have a problem with the show, but I think it is a little young for her (she's 7 1/2). I told her that she wasn't a little girl anymore and the following conversation took place:

Me: "You're not a little kid anymore"
LS: "Yes I am"
Me: "No, you're a middler"
LS: "But I'm not a large, I'm a medium which makes me small."

The conversation ended at that point and I told her she could watch "Little Einsteins". I can't argue with that kind of logic. :-)
