Is that right? Did you really say that?

I told my dad I had breast cancer first, then my sister.  She said "Is that the official diagnosis?"  I said yes, I needed surgery, chemo and radiation. She said, "Well, the chemo and radiation are going to kill you anyway."  I didn't say anything but the next day she said she wanted to apologise as she MAY have said the wrong thing! Possibly!
I quite liked the response from a 'friend' whose brother I had been dating. Sadly his wife had passed away early in their marriage in a car accident.  When I told my friend she said "Maybe it's best if you just stay as friends with my brother …. He's already had one wife die on him."  I thanked her for her thoughtfulness, but until then hadn't really considered dying … especially not on top of someone!
