The budding reindeer expert

Me: Hannah, it's only one week until Christmas Eve!
Hannah: I KNOW THAT!
Me: Oh, well alright then.
Hannah: And we'll make cookies for Santa, and leave carrots for the reindeer.
Me: Yup! Then when you wake up on Christmas morning, you can come wake us up and we'll go downstairs and see if Santa came!
Hannah: Yup, we'll go outside and check for tracks.
Me: What?
Hannah: We'll go outside and see if there are sleigh tracks and deer tracks.
Me: Well, I meant that we'd go see if Santa left you anything under the tree...that how we'll know if he came.
Hannah: Yeah, I KNOW that...that and the deer tracks.
Me: I'm pretty sure that Santa and the reindeer land on the roof...so we won't be able to see any tracks honey.
Hannah: No...they land on the lawn and go across it and then the reindeer jump really hard and pull the sleigh up to the roof. So we'll see those tracks.
Me: I think they just fly around and land on the roof.
Hannah: No, that's silly. Deer can't fly, they can just jump hard.
