Sometimes, trying to protect parents can be wrong. A couple of years after my Mum died, I became quite poorly - did not tell my Dad any of it as I was concerned about worrying him. When I needed to have quite a major operation for this condition, again I told him nothing about it - just telling him I was going into hospital for a small procedure for 'womans problems'. My condition had nothing whatsoever to do with my gender!!
Anyway, my poor Dad (83 yrs 0ld), turned up at the hospital the day after my op. I was in Intensive Care -my children were being told to say good bye to me each time they left.
I did survive (obviously), and still feel so guilty about my poor Dad and the total shock he had. A few months later he told me he only had his cat to talk to. My children were all too much in shock themselves to take into account the need to help their grandfather.
On the other hand, my eldest daughter got herself into some problems with the law soon after I came out of hospital,. She was always my Dads favorite, (he had been the first person to hold her when she was born). So pleased that I kept all that from him, as he died a few months later. She turned her life around totally and often says to me that she is pleased that Grandpa never knew of that bad time, but she wishes he could see how well she is doing now - nearly thirty years later.
Must admit I do say to my adult children that I do not want them to protect me from anything which is going wrong in their lives. I have told them that if they do not tell me such things -then I will just spend more time worrying about what they are NOT telling me!!!
