Actually, at the time of the transplant I had already planned to give my donor a gift of $1000 on the anniversary of the operation every year for the rest of my life.
Now he has taken to calling me repeatedly at about 5 AM asking for more money ...
Could you please give us a little more information on how your donor came into your life? It all seems very shady.
Thanks for all your advice and comments. I have not paid him any money since receiving his phone calls, and I have not yet decided whether I should continue with my original plan to send him $1000 a year on the anniversary of the transplant or not, given that he seems to view thiis gift as an invitation to exploit me rather than as the expression of gratitude I intended it to be.
Someone made the related comment earlier that these payments post-transplant could be deemed to be payments for the transplant on an installment plan. But if you consider how an installment plan works, you will see that this is impossible in the case of a kidney transplant. First, the person from whom you buy something on an installment plan needs insurance that you will not default on the payments, and this insurance exists in the form of his right to repossess the goods purchased which you have in your possession. But with a kidney, it would be impossible and an illegal assault for the vendor to take the kidney back out of your abdomen, so without the insurance of the possibility of repossession, no kidneys could be sold on installment. Second, a sale of something on installment requires the backing of the judicial system, which will enforce the contractual obligation of the buyer to continue paying the installments or forfeit the purchased item. But no court will enforce a contract to purchase a body part, since such a contract, being against public policy, would be void, so again, there is no way to sell a kidney on the installment plan.From this it follows that post-transplant payments can only be gifts, not purchase money.
