It seems like everything sleeps in winter, but it’s really a time of renewal and reflection...

 My boy Robinson:

In a drear-nighted December, 

Too happy, happy brook, 

Thy bubblings ne'er remember 

Apollo's summer look; 

But with a sweet forgetting, 

They stay their crystal fretting, 

Never, never petting 

About the frozen time.     

John Keats
