"How can I tell that someone is lonely?
It is not because of tear stains on their face.
Or the strain of years on their shoulders.
It is not because they sit alone apart from friends or because they read books about remote stars.
It is not because they are isolated. And it is not because they say so.
They never do.
How can I tell that you are lonely?
You smile so often, dear.
Nobody shares happiness as freely as you do."
