A small bit of personal advice
I grew up with my grandfather who served in Europe in WWII. Got to hear all kinds of stories growing up. The best ones were about flights to Ireland and Scotland, and the friends he made with the RAF, Free French and Polish pilots. His plane got shot up and his back broken and he was shipped home in 1944, but the best stories were about his fellow airmen and English, Scottish and Irish people he came into contact with.
He's 88 and almost gone. Alzhiemer's set in and moved fast. Probably a matter of weeks now.
Here's my advice: If you have any family members that served in World War II, talk to them, learn their stories. It may be real to many of us, but to our kids it's like the Civil War.
And tell your loved ones what they mean to you NOW, while they can understand. One thing that makes my situation just a little easier to handle is that there is absolutely NO DOUBT that my grandfather knew just how much I loved and appreciated him. And I know he was proud of what I had accomplished. Believe me, I have no regrets, nothing left unsaid, and it makes dealing with this easier.
Just my 2 cents.
