What Will They Do?

What will they do when I am gone? It is plain
That they will do without me as the rain
Can do without the flowers and the grass
That profit by it and must perish without.
I have but seen them in the loud street pass;
And I was naught to them. I turned about
To see them disappearing carelessly.
But what if I in them as they in me
Nourished what has great value and no price?
Almost I thought that rain thirsts for a draught
Which only in the blossom's chalice lies,
Until that one turned back and lightly laughed.
