Neither did I until I googled it! There's nothing enigmatic about it though, but having found it I now feel obliged to post it.
by Margaret Widdemer (1884-1978)
She always leaned to watch for us,
Anxious if we were late,
In winter by the window,
In summer by the gate.
And though we mocked her tenderly,
Who had such foolish care,
The long way home would seem more safe
Because she waited there.
Her thoughts were all so full of us,
She never could forget!
And so I think that where she is
She must be watching yet.
Waiting till we come home to her,
Anxious if we are late,
Watching from Heaven’s window,
Leaning on Heaven’s gate.
I think that's beautiful Aileen! I know it's about 'mother love', but I realised it could equally apply to my dogs!
They are never happy till 'all' the sheep are safely in the pen!
Thanks for posting The Tyger too Aileen. It's always been a favourite of mine!
