What a hug is.

The Hug
It was your birthday, we had drunk and dined
Half of the night with our old friend
Who'd showed us in the end
To a bed I reached in one drunk stride.
Already I lay snug,
And drowsy with the wine dozed on one side.

I dozed, I slept. My sleep broke on a hug,
Suddenly, from behind,
In which the full lengths of our bodies pressed:
Your instep to my heel,
My shoulder-blades against your chest.
It was not sex, but I could feel
The whole strength of your body set,
Or braced, to mine,
And locking me to you
As if we were still twenty-two
When our grand passion had not yet
Become familial.
My quick sleep had deleted all
Of intervening time and place.
I only knew
The stay of your secure firm dry embrace.

Thom Gunn, from The Man With Night Sweats

This is perhaps my favourite full length poem from this collection, which I've quoted before.  It's a beautiful, peaceful image a relationship.  Safe, close, warm, held and loved, yet still surprised and surprising.  I also love the idea of a 'grand passion...become familial'.  He's a very direct poet - there's no beating about the bush or confusion in his imagery.  The poetry comes from such subtle use of words that you barely notice how your reactions are steered.  I particularly like the use of the words 'stay' and 'dry' in the last line, which seem to me to suggest something of death.  The whole seems to conjure up something of Larkin's 1964 poem 'An Arundel Tomb', though that might just be me:

An Arundel Tomb
Side by side, their faces blurred,
The earl and countess lie in stone,
Their proper habits vaguely shown
As jointed armour, stiffened pleat,
And that faint hint of the absurd —
The little dogs under their feet.

Such plainness of the pre-baroque
Hardly involves the eye, until
It meets his left-hand gauntlet, still
Clasped empty in the other; and
One sees, with a sharp tender shock,
His hand withdrawn, holding her hand.

They would not think to lie so long.
Such faithfulness in effigy
Was just a detail friends would see:
A sculptor's sweet commissioned grace
Thrown off in helping to prolong
The Latin names around the base.

They would not guess how early in
Their supine stationary voyage
The air would change to soundless damage,
Turn the old tenantry away;
How soon succeeding eyes begin
To look, not read. Rigidly they

Persisted, linked, through lengths and breadths
Of time. Snow fell, undated. Light
Each summer thronged the glass. A bright
Litter of birdcalls strewed the same
Bone-riddled ground. And up the paths
The endless altered people came,

Washing at their identity.
Now, helpless in the hollow of
An unarmorial age, a trough
Of smoke in slow suspended skeins
Above their scrap of history,
Only an attitude remains:

Time has transfigured them into
Untruth. The stone fidelity
They hardly meant has come to be
Their final blazon, and to prove
Our almost-instinct almost true:
What will survive of us is love.

Philip Larkin, from The Whitsun Weddings (London, 1964)
