There seem to be two questions here: 1) Should I consider giving a gift to someone with whom I choose not to have any further contact; and, 2) How can I give such a gift? Here is my answer to the “should” question: Forgiveness is about giving, even to those with whom you are angry and estranged. This is part of the paradox of forgiving: As you reach out in goodness to those who were not good to you, then you experience psychological healing. Therefore, it is morally appropriate and psychologically prudent to consider giving a gift, if you choose to forgive. The second question, regarding how it is even possible to give a gift to someone whom you will not see again is this: You can contribute to a charity in the person’s name. You can pray for the person if you have a religious belief. You even can say a kind word about the person to someone else.
