While volunteering in palliative care, some of my most sacred moments were in offering foot massages to patients. When they said they would appreicate a massage, they were very open and found it to be extremely relaxing. Some had never had massages in their lives, but had discovered in the hospital how much they loved the experience and looked forward to it. So I would offer a foot and/or hand massage. It is a very intimate way of expressing love.
Song and music can also be a very special gift. Perhaps singing a song which your loved one greatly appreciates would be a gift of love.
