Is Santa Real?

The other day Ellie and I were driving in the car when Ellie asked me about Santa.

"Mom, is Santa real or just a person?" (I was freaking out thinking oh no - not already!)
"I think he's real Ellie, why do you ask?"
"Because I've never seen those clothes in a store. (pause) So I think he changes them with his magic or something."

I love it. What a thinker. This kid may have been shopping one too many times.
