well i am so sorry to hear this. i know he had been ill and that tricia had spent time caring for him. my sympathy and prayers go to her and her family at this very sad time.
Tricia deserves a medal for the selfless and low-key way in which she supports those who need her. When I learn of the things she does for others (quietly and with a complete lack of needing recognition for doing so), it makes me feel very humble indeed.
