My mum did the same thing on the day after Christmas 16yrs ago now, we went to see her in hospital and was told she was going down to the operating centre and we should come back later. So we said see you later gave her a kiss on the cheek and a tear rolled down her face, I had a funny idea but said nothing to my daughter and we left decided to go look at the shops, then got a phone call saying hurry up back as she wasn't doing to well. So we jumped in the car and got stuck at some traffic lights I looked at my daughter and we both said the same thing when we got to the ward they said she died 10mins ago. That was when we was at the traffic lights. I was gutted she was my best friend in the world.. but she didn't want to go on anymore at 93 years old. I can't say I blame her she did have a very hard life when she was young. So I understand how you all feel..
