How old was your father’s friend when that happened.
They have pointed out that this guy was a ripe age for the onset of schizophrenia and the like.
I just remember he was one of the funniest people you would ever want to meet. Always had a joke to tell and it was always a good one. The last time I saw him, he was a shell of himself. Very angry.
I just remember overhearing conversations between my parents. His wife was a nurse and was constantly nagging at him about health stuff, cholesterol, etc. Was always limiting his diet. One day he brought home a carton of eggs (which she would have never let him eat) and cooked the entire dozen and sat down and ate them in front of her, which led to a huge fight. It was just weird stuff like that.
