I wish mum had talked to me about what she would have wanted. By the time mum got to last stages I just had to go with what I thought/hoped were her wishes.
If you write it down, please give it to someone for safekeeping. I know that mum had written down directions for her funeral, including hymns and what to do with her ashes, but I never found it. I can only think that when she got to the late stages she got confused and threw it away.
