The hatred of a mother

Her wavering smile,
A mother's pursed lips,
Peace had lasted for a while,
But the axis shifted on its head,
"Better off dead",
That was what mother said,
And when the night was through,
She thought 'daughter who?'
Whilst below the bridge,
Deep down the river,
A single body sunk,
One lonely daughter,
Snapped out of her funk.
