Happiness can mean many things, not least that of meeting someone with whom one desires to spend their life; in this some of us are fortunate and some of us are not - through no fault of their own, or possibly through some fault of our own.
For those who have unfortunately missed that one important person in their life - and are left with but memories - the following song sung by Harry Nilsson probably will resonate.
"Gone is the romance that was so divine.
'Tis broken and cannot be mended.
You must go your way,
And I must go mine.
But now that our love dreams have ended...
What'll I do
When you are far away
And I am blue
What'll I do?
What'll I do?
When I am wond'ring who
Is kissing you
What'll I do?
What'll I do with just a photograph
To tell my troubles to?
When I'm alone
With only dreams of you
That won't come true
What'll I do?"
So, what do we do?
