If its someone you are still in contact with it might just be to right any lingering wrong / discord / or doubt about how you feel about them. Perhaps by giving them a slightly bigger hug than usual and telling them ts good to see them.
Amends are not the same as apoplogies. They are more showing willing to put right past harms or hurts. Perhaps you and your sponsor will just decide that you are already making living amends by letting bygones be bygones, choosing to let go of any resentments held against that person and striving towards love and unity with them, for the sake of all involved.
A lot of my amends ended up being 'Living' amends. I thought that was great til I realised its an ongoing job and not necessarily the easiest option after all. Haha.
