The Caller With No Voice

The phone rings and I pick it up,
My greeting is met with silence,
I repeat my 'hello' once more,
Again silence meets my ear,
And just as I'm about to say something else,
The line goes dead...

The last time I received a call like that,
Was over four or five years ago,
I know who the caller was that time,
Who's to say they haven't done it again?
It can't be a coincidence that the call came,
So soon after she was spotted nearby...

I have every right to be suspicious of this call...
It looks like something big is about to happen...
The caller with no voice looks set to appear very soon...
