My grandfather was not loved by all, but respected by most I think. He definitely was a tough, mean old bastid when he wanted to be.
He fought in WW2, somewhere near Japan his plane (he was belly gunner I believe) made an emergency landing. He didn't like talking about what happened after landing, in a jungle somewhere but he said it was hell. He was shot in the leg, survived and made it home eventually. Once home he bought a foundation with just a roof on it and started having kids, and building the house as the family grew.
Wife number one made 4 kids, then he met my grandmother while learning how to sign as he was mostly deaf from the war. My grandmother was almost entirely deaf since childhood, and together they had 12 kids. So the house he built ended up being something like 3500 sq ft. He worked for the post office driving trucks until he retired, but he was always swinging a hammer until he was in a home in his 80s.
