Sees’n’esses

The silent snow settles on the creature’s special Christmas tree
The creature being a creation created by me
My creation sees the season as the season should be seen
Seeing hope, seeing magic, in the special season’s scene
The silent snow settles, carpeting the creature’s comfy lair
With excessive season’s sees and esses cascading everywhere
But two special sees and esses surround a special time
And that special  time is Christmas, as seen on the very first line
