That sucks, best of luck with that, I hope he stays positive and has a happy remainrer of his life. I never knew either of my grandfathers unfortunately. One died before I was born, the other very shortly after I was born... Both from smoking related illnesses. Actually... I don't think my paternal grandfather was really my biological grandfather. I suppose it is possible my biological grandfather is still alive somewhere but he'd be very old now if he were.
My Grandad died last year mate at 92 years old. He was a former Dam buster and one of the hardest men physically and mentally anyone could ever meet but also the most kindest gentle man at the same time. Men like him and probably your grandad arent made that way now, they were cut with a different cloth. If the second world war was to kick off again tomorow we'd get our ar$es kicked because the country is now full of wanna be playboys and pussys that cant physically fight man to man unless they have half a dozen mates with them. He was/is my role model in life and it still breaks my heart daily that he is no longer with me. I feel your pain mate, your heart will heal but never fully recover.
I went and saw my grandfather yesterday, It was the best day of the year for me, He didn’t look well, He spoke well, It was slow, We had a laugh, He told me stories that I couldn’t remember, He shook my hand, I’ll never forget that, Yesterday was a good day for me personally.
My brother was admitted to a care home last year, it’s a permanent residence, he is 59. He has a rare mental health condition that means he can remember vividly what he/ we did from when we were kids up till the last 10 years. Anything more recent than that he can’t recall or retain the information - so every time I see him he can’t remember the last time I saw him or what we did. It can be soul destroying, especially when he asks where our mum is, as she passed 3 years ago. Genuinely sorry for your loss Les
