As I was a wand'ring ae midsummer e'enin',
The pipers and youngsters were making their game;
Amang them I spied my faithless fause lover,
Which bled a' the wounds o' my dolour again.
Weel, since he has left me, may pleasure gae wi' him;
I may be distress'd, but I winna complain;
I flatter my fancy I may get anither,
My heart it shall never be broken for ane.
I could get na sleeping till dawin' for greetin',
The tears trickled down like the hail and the rain;
Had I na got greetin', my heart wad a broken,
For, oh! love forsaken's a tormenting pain.
Although he has left me for greed o' the siller,
I dinna envy him the gains he can win;
I rather wad bear a' the lade o' my sorrow
Than ever hae acted sae faithless to him.
Weel, since he has left me, may pleasure gae wi' him,
I may be distress'd, but I winna complain;
I flatter my fancy I may get anither,
My heart it shall never be broken for ane.
