Is that why?

Long long ago, on a starry night,

When a rain drop, from the lap of a cloud

Looked down and saw in the deep dark woods,
A lonely white withering rose, sleeping amidst the thorns,

And went with the breeze to touch her face,

And with his cool silver lips, kissed her weak pale cheeks,
The leaves giggled, 
The moon smiled 
and the brook was mute….

And in the serene silence, the rose wake up in shock

And for a moment, went to a daze

But

Slowly then shyly she smiled, and beautifully she blushed

And did her cheeks glow rich deep crimson ….

        So is that the reason why roses are red???
