Bittersweet

I was inspired to write this today, I'll tell the story afterwards if you like...
Bittersweet
I passed her in the hall today
She smiled sweetly and said "Hello"
I grinned back and replied
As my heart sang and my feet began
To walk on air

The Feeling faded moments later
As I realized
I would never move in your circles
It would never be more than
A friendly "hello" and bright smile

I would give just about anything
To read your mind for just a moment
To see if that smile means more
That will never be
I must accept this

I will be Cyrano to your Roxanne
Loving from afar
Loving by proxy
Worshiping her smile
Because that's all I'll ever have.

Please tell me what you think..should I keep writing these, or quit
while I'm ahead?
