Classic Poem

I think and think; yet still I fail—
Why does this lady wear a veil?
Why thus elect to mask her face
Beneath that dainty web of lace?
The tip of a small nose I see,
And two red lips, set curiously
Like twin-born cherries on one stem,
And yet she has netted even them.
Her eyes, it's plain, survey with ease
Whatever to glance upon they please.
Yet, whether hazel, grey, or blue,
Or that even lovelier lilac hue,
I cannot guess: why—why deny
Such beauty to the passer-by?
Out of a bush a nightingale
May expound his song; beneath that veil
A happy mouth no doubt can make
English sound sweeter for its sake.
But then, why muffle in, like this,
What every blossomy wind would kiss?
Why in that little night disguise
A daybreak face, those starry eyes?
