Yesterday would have been my dad's birthday. He would have been 98 although sadly he died in his late 60s in 1987 from a heart attack. I can't imagine him being 98. He died young but he was otherwise healthy to his end.
I regret not speaking to him about his Pathfinder years in the RAF. There were brave young men on both sides in WW2. Dad did not like to speak about those days. Looking back he was very very brave.
The war years impacted him greatly and he was happy not to be reminded of them. The funny thing is if he walked in the door now it would seem so natural. There is so much I'd want to talk with him about.
If your parents are still alive ask them the questions before it is too late.
