I have remembered when the winter came,
High in my chamber in the frosty nights,
When in the still light of the cheerful moon,
On the every twig and rail and jutting spout,
The icy spears were adding to their length
Against the arrows of the coming sun
- from Winter Memories by Henry David Thoreau.
Yes, it's Midwinter's Day, the Winter Solstice, the longest night... everything gets better and brighter from this point on.
Or so they say.
