Wuthering Expectations: A little spare the night I loved, \ And hold it solemn to the past. - Christmas and context

Wuthering Expectations: A little spare the night I loved, \ And hold it solemn to the past. - Christmas and context
Excerpt:
Well, from the road, the lanes or the common,
In came the flock: the fat weary woman,
Panting and bewildered, down-clapping
  Her umbrella with a mighty report,
Grounded it by me, wry and flapping,
  A wreck of whalebones (47-52)

Pretty good, but not really very Christmasy, is it?  And most of the poem is not descriptive but argumentative.

I was surprised to find so much about Christmas in Tennyson's In Memoram (also 1850).  Three Christmas scenes provide one of the few concrete structural devices in a mostly abstractly structured poem.  From the third Christmas:

The time draws near the birth of Christ;
  The moon is hid, the night is still;
  A single church below the hill
Is pealing, folded in the mist (Stanza 104).

Which is nice enough, I guess, but treating a chunk of this poem about grief and loss as Christmas decoration seems misguided.  This particular Christmas is the third since the loss of Tennyson's best friend, so the theme is acceptance:

Let cares that petty shadows cast,
  By which our lives are chiefly proved,
  A little spare the night I loved,
And hold it solemn to the past. (105)
