Ahh, but you haven't heard the WEIRD part! We had Hannah by herself (without her older sister) a few weeks ago, and it was like a completely different kid! Think of the little girl in every McDonalds, Barbie, or My Little Pony commercial, wrap them all in to one red-headed cutie, and you've got the sister-free version of Hannah.
Re: I refuse to believe this child exists.
Scares me... I think she's up to something.
