Hoarse Play

I lost my voice, but you found it.
You picked it up, dusted it off,
And put up posters on poles
With a picture and a number.
So I gave you a call,
But with no sound in my mouth,
I could not say what about.
However, you somehow knew
The nature of this call.
Putting the words right back
Where they belong.
Because even in silence,
You get it.
And without explanation,
You know.
