You were blessed to have known them. I never knew either of my grandfathers. My mom's dad died as a result of a copper mining accident when she was about six. And my dad's dad was an illegal alien who got sent back across the border when dad was just a boy.Lost my paternal grandfather to a brain aneurysm. He was about 72. I was in the second grade at the time. My maternal grandfather was 82 and I was a sophomore in high school.
