Fairy tales that always end with "they lived happily ever after" is what we always look forward in it no? I didn't get to hear those fairy tales as a kid but as a young adult, still, even I enjoy it a lot. The satisfaction and heavy weight that was lifted after the main characters gets the beautiful ending they deserve just gave me those pretty feelings.

And its Baby Jesus to you not Santa? But yeah, same, same, a lot of kids really believe that it is like magic, gifts will just appear and it will makes everyone excited and happy.
