INTERPOLATION
Nancy McLehose (Clarinda) sent a couple of verses to Robert Burns which she entitled “Talk Not of Love”. Burns added a couple of verses of his own:
“Your friendship much can make me blest, O, why that bliss destroy! Why urge the only, one request You know I will deny!
Your thought, if love must harbour there, Conceal it in that thought; Nor cause me from my bosom tear The very friend I sought.”
