You never know

You never know when someone
May catch a dream from you.
You never know when a little word,
Or something you may do
May open up a window
Of the mind that seeks the light
The way you live may not matter at all...
But you never know - it might.

And just in case it could be
That another's life through you.
Might possibly change for the better
With a broader brighter view.
It seems it might be worth a try
At pointing the way to the right.
Of course, it may not matter at all,
But then again it might.
