I feel for you

I know you feelings. I just came back from Beijing. I went to see my uncle, who is with advanced stage of liver cancer. My uncle told me that he is not afraid of death but the pain in the process of it. Please make sure your sister has good pain management available (Nowadays hospitals in China have extra tight controls for narcotic pain killers), and make wise (sad nonetheless) decision when it is time to let go. May God take care of good people.
