"Sigh No More, Ladies..."

(From "Much Ado about Nothing", "Mucho ruido y pocas nueces")

Sigh no more, ladies, sigh nor more;
Men were deceivers ever;
One foot in sea and one on shore,
To one thing constant never;
Then sigh not so,
But let them go,
And be you blithe and bonny;
Converting all your sounds of woe
Into hey nonny, nonny.

Sing no more ditties, sing no mo,
Of dumps so dull and heavy;
The fraud of men was ever so,
Since summer first was leavy.
Then sigh not so,
But let them go,
And be you blithe and bonny,
Converting all your sounds of woe
Into hey, nonny, nonny.

¿Para qué preocuparse por los hombres?
