Expecting a Letter

The strangest thing happened today,
An invisible mail man came my way.
He handed me something that wasn't quite there.
And mail like that is really quite rare.
So I opened the nothing ever so wide,
To find even less than nothing inside.
Every line so neat and clean,
Not even a single word could be seen.
A scent so sweet as I recall,
A fragrance so light, it was nothing at all.
So I'm writing you back with love you can bet,
Saying thanks for the letter I never did get.
When you get this poem, read it through,
And take the advice that I give to you.
I could be out there where things are much better,
And you could be here expecting a letter.
