I know this sounds sickly sweet, but "Julie" (name changed) was my best friend's sister many years ago.

All alone without a friend,
Will this sadness ever end?
Then one day a friend she finds,
Our Julie, who is four - and blind.

She brings him in - his name is Jim,
Asks, "Can I have some food for him?
He's lost with nowhere else to go.
I'll keep him and I'll love him so."

What can you say? Your heart could break.
And all your life you'll feel the ache
Of hearing "Don't sit in my chair,
Jim's sat there," - BUT THERE'S NO-ONE THERE!
