I was at the hospital with him until his children (grown-up) got there and I took some food round last night. I don't want to crowd him though so have called him today to say if he needs anything to let me know and that I will come round in a couple of days. Is there anything anyone thinks I should be doing/saying? What can I say? I feel useless and helpless but I don't want this to be about me and my feelings, but do what's best for poor David.
