la donna è mobile

by Giuseppe Verdi [1813-1901]

One working translation:

Woman is as fickle
as a feather in the wind
Silent in speech
and in thought!
Always lovable
the beautiful of face
whether crying or laughing
is lying
He is always miserable
who trusts her
whoever confides in her
his unwary heart!
And yet he will never feel
the complete happiness
who on that breast
does not drink of love!
