A woman I have known for many years and who helped look after my mother has just had her leg amputated. However, I have invited a schoolfriend to stay that weekend, and she has pancreatic cancer. Would it be very rude to go to the party for a short time? I have a charming, polite, gay man as my other house guest to keep my schoolfriend company. What should I do if I run into him in the market in the main square?
