He is of illustrious name, / Free from spot, and free from blame; / Bred as noble minds are bred, / Leading, too, as he was led: / Yet I love him not—and I / Know full well the reason why! / When he smiles, delight is nigh; / Joy salutes him, passing by; / Pleasure in his steps is treading, / And his friendship, 'tis an Eden: / Yet I love him not—for I / Heard him call me false—that's why!
