person A: It was really tough to watch my father struggle with cancer. When he got the diagnosys I was devastated for him.
person B: I am sure that was difficult.  How is he now?
person A: He passed away. At least he is no longer in pain.
person B: I am so sorry for your loss.  It can be a relief to know he isn't in pain.  I felt the same way when I lost my Aunt last year.  She was like a mom to me.
