Hi nannon, i am sorry that you have lost a your grandfather and i know your parents will be very deeply upset, grief is a strange thing.
My family lost a very close friend just over a week ago, I was unable to function much for a few days but a week ago Sunday I did put a thread up in the Family Life section relating the details and asking for advice on how we could tell my grandson that his Godfather was dead. I had some lovely replies over last week, and people were very concerned. I certainly woulkd not have put the thread in this section, which is a sad thing, but I wouldn't have done.
We are going to see him at the Chapel of Rest this evening and the funeral is on Friday. Sometimes shock makes you confused and unable to think straight, I know my son has been in a state of shock all last week and it has been rotten to see him coping with his grief. I hope you are there for your family and will be stepping up to carry your grandfather on his last journey, that's what you could focus on.
