Since this thread continues and we are introducing our extended families, I'll add this...
Father's side:
My grandfather was a carousing alcoholic who later found religion and used to deliver pies and cakes to neighbors in his old age. He became a very good man in his later years. His name is on one of the bricks in the First Baptist Church in his town. He always gave me a Silver Dollar when I visited him and took me with him when he painted houses. I only saw the good side of him.
His carousing had already driven my grandmother crazy. She was nothing short of psychotic and she would say horrible things to my mother and never treated her well. She used to sit me on her lap and tell me how I would go off to war and be killed. (Nice!) One funny memory... She wore lots of powder and my grandfather used to say "you look like you just dipped your head in a flour barrel." She later developed Alzheimer's disease and passed away in a nursing home. Perhaps what I experienced was the early stages of this horrible disease.
Mother's side:
My grandmother contracted rheumatic fever and passed away from heart disease when I was very young.
My grandfather got remarried to a woman that was at least 20 years younger. Growing up, his children always fought for his attention because he wanted it that way. They were so competitive that none of them were close. My mother got close to her brothers as they got older, but when her sister passed away she didn't even care. She hated her sister because she went to college. My grandfather put my step-grandmother through hell, demanding that she cater to his every whim, especially in his declining years... and she did it until she was completely worn out. He was good to me, but I saw how he treated his wife. Talk about a dysfunctional family.
So, my father had to grow up with these parents, and two alcoholic brothers, and was able to rise above it all. I have so much admiration for him. I'm not sure I could have done the same. My mother had very little chance from the start because she came from a dysfunctional family and married into one. I admire her for doing the best she could under the circumstances.
I'm happy to be a relatively normal, caring person. I chose my own path.
