People respond to shock in different ways I know, want to say that first.
This morning we heard a childhood family friend had died of cancer. She was 59. My sister in particular adored her as a child. Didn't see much of this lady in adulthood except hearing updates from parent's but when I told my sister the bad news just now, she looked at me and said 'OK. That's just really sad.' and didn't really react. I was just surprised and also a bit worried. She is normally very emotional.
