Slipping Away

If I should dare to be so bold, I say:
Have you ever met a man quite like him,
Whose heart and mind was so gold or akin?
Whose allure was strong and sure as the day?
He, that whom you cannot resist his ways
Whose tempting touch, though pure and such, is sin,
With a wit to turn days upon his whim,
Such that you cannot hope to stay away?
He is fleeting, upon a leaving train,
Which you cannot catch if it does depart,
And tomorrow he may well be far gone.
As such, to not see tragedy again,
Pertinently follow after your heart
For any other choice would just be wrong.
