Watching A Miracle on 34th Street last night, my wife kept cracking up at Mara Wilson's ultra-precocious 7 year old. You can't really blame her. Only John Hughes could have written a child like this:
Kris Kringle: Oh, Susan. Just because every child doesn't get his or her wish doesn't mean there's not a Santa Claus.
Susan: I thought you might say that.
Kris Kringle: Did you? Yes. Well... A house is a very big order--
Susan: And very expensive.
Kris Kringle: And a baby, well a baby takes almost a year to, uh, to, uh...
Susan: nine months. More if the lady's late. Less if the baby's a preemie.
The funny thing is, I would bet cash money that my wife was exactly like this when she as 7 years old too.
