Well, you can read the Scottish version to i ply some kind of sinister role for the lady - but I think Bill D's reading is more poignant - "a word picture of 'the way it is' with death in battle sometimes. Once he is gone, those who used to care soon forget."

A bit like AE Housman's "Is my team ploughing" really, in The Shropshire lad

'Is my team ploughing,
That I was used to drive
And hear the harness jingle
When I was man alive?'

Ay, the horses trample,
The harness jingles now;
No change though you lie under
The land you used to plough.

'Is football playing
Along the river shore,
With lads to chase the leather,
Now I stand up no more?'

Ay, the ball is flying,
The lads play heart and soul;
The goal stands up, the keeper
Stands up to keep the goal.

'Is my girl happy,
That I thought hard to leave,
And has she tired of weeping
As she lies down at eve?'

Ay, she lies down lightly,
She lies not down to weep:
Your girl is well contented.
Be still, my lad, and sleep.

'Is my friend hearty,
Now I am thin and pine,
And has he found to sleep in
A better bed than mine?'

Yes, lad, I lie easy,
I lie as lads would choose;
I cheer a dead man's sweetheart,
Never ask me whose.

I'm hoping the line breaks come through there from the site I lifted it from. If not, "I'll be back", as the man said.
