morgana a friend of ours simply didn't have the energy to see people most of the time, no matter how close they had been. He also wanted to spend time just with his wife and just 'being' in his home. We phoned and spoke with his wife, also,a close friend, often. Sometimes he would say 'hello', no more than that, sometimes he didn't want to speak, or indeed couldn't speak. We kept in touch with cards, Some with images of places we had been together some gently humerous which he enjoyed, although not everyone would I know. His wife let us know if there was a time he could cope with a very short visit but as his illness progressed we couldn't see him at all. Hard after 40+ years of friendship. It is very difficult when our instinct is to be there. Maybe your daughter could speak with her friend's family and explain of course she will respect her friend's wishes, that she is thinking of them all and if her friend would ever like to see her then of course she will be there. In the meantime send cards, according to her friend's character, it is a very sad time for you all.
