We tried doing the super-comfortable thing with my dad. (EC Stage III) We just wanted him to take it easy and get better. What I discovered was that the more "normal" things were, the better Daddy did. My philosophy is this: Cancer makes you and everyone around you realize how completely helpless we all are to fight this beast. Daddy cannot control the cancer, but he can control other things. So we let him control the things he wants to and we pick up the slack on everything else.
I will be praying for you and your friend!
