Thanks for the comments to my sister and her going back to work dilemma. I have had a chat with her and she is adamant now that she is staying at home.
I was worried about her as I know what she's like, I call her Florence Nightingale !
Once a nurse always a nurse , prefers looking after others than herself. She stood by me when I was in and out of trouble, so I owe her thanks and gratitude for that.
