What is it about the unattainable that makes us want it so much more?

On that rainy day in January,
I saw you standing in line,
Waiting to pay
For the book.
You know the one.
It's been whispering sweet promises
In my ear.
How it will be the best I ever have
It will imprint on me.

I tried to resist the allure
But it's elusiveness pulled me in
Like coiling tendrils
Of immeasurable strength.

I dreamt about that book
Waited for it to come to that store
And there you were
Buying the only available copy.
I knew then
That I wanted you both.
I followed you out
Having a witty dialogue in my head
You would be snared by my charisma
I would get my book.
You stopped at a black car
The passenger door opened.
Out stepped Delilah
the woman that kills dreams.
