Ambitions of a 4 year old

Today on the way to daycare my 4 year old informed me of his future ambitions.

"Mommy, when I get big I want to be a Polar Express man!"

At first I thought he possibly meant he wanted to be a train engineer or something. But I quickly scrapped that idea.

"Then when I get even bigger I'm going to be Cat in the Hat. And then when I get really big I'm going to be the Grinch because the Grinch is really really big!"

I guess it could all come true though. I see a stage and bright lights in his future!
