Imagination

My three year old has gotten to an age where her imagination is interesting...she has an imaginary friend (superman-i wonder who's fault is that?), she makes her toys talk (i mean she has whole conversations with them), and she comes up with the funniest stories. Here's the story of the day:

She says that the man is in a truck, next to the street that has a door...oh no, wait...the door on the street is his personal elevator now. Then she introduces me to his mother and his friend whom are also riding in the car, sorry truck, with him.

Children are so smart...where do they come up with this stuff? I'm such a proud mother...
