The Duenna, Song from. 
By Sheridan, Richard Brinsley. 


Had I a heart for falsehood framed,
I ne'er could injure you;
For though your tongue no promise claimed,
Your charms would make me true.

To you no soul shall bear deceit,
No stranger offer wrong;
For friends in all the aged you'll meet,
And lovers in the young.

But when they learn that you have blessed
Another with your heart,
They'll bid aspiring passions rest,
And act a brother's part.

Then, lady, dread not here deceit,
Nor fear to suffer wrong;
For friends in all the aged you'll meet,
And brothers in the young.
