As Christmas becomes more tangible, Fleur has gotten more excited. Like 12 dimension strings, she was vibrating with excitement.

The neurotransmitter for anticipation was clearly in effect. The clockwork of her mind churned over what she will get from this.
The first Christmas was her trying to crawl to the tree. And playing with wrapping paper. The second was playing at tearing open gifts.
This one she understands the concept. And is all in.
