Fine young one.

I´m not too aware of the yearn or the crush.
I´m told they lose it in an instant like the toilet flush.
Not aware of the admiration some fine young one might have.
Every little flirt or smile, don´t quite know to grab.
Faced with some fine young girl, I know not how to act.
I´m searching for my charm, yet all I access is lack.
Yes I´m not too aware of the yearn or the crush.
How to tell a girl is ansy or if it´s anger or just a blush.
