My parents weren't really bad, per se. Just cold.
Dad was a milkman, worked early morning and went to bed early. Mom was the 1950's suburban parent. A bit overwhelmed I think by 3 boys (I was # 1 in time but not affection). #2 was Dad's favorite and #3 was Mom's. #3 was spoiled rotten. He had "problems", and was "misunderstood" according to Mom. #2 was the Boy Scout, Dad was Troop Leader, went to his school functions, etc.
I remember several times when I was punished for something #3 did. Mom would find out but never apologized. He got rewarded for "C's" and I got punished for "B's".
As I've told before, I went back to school in my 40's, earned a BS in Marine Biology and an MS in Biology (Black Bear Behavior), all with honors or high honors. Mom went to graduation, but paid more attention to #3's kids. I remember trying to show her my Thesis (all bound so pretty) and all she wanted to talk about was the kids doing a skit for the Fourth of July. She never told me once that she was proud of me (I'm still the only one who graduated college).
Just before she died, she asked us to go back to SoCal. She asked for some tortilla soup and I made her some home-made soup according to my recipe. My wife took her into the shower and washed her and her hair. She died that night. #3 had lived with her, rent free (he was "disabled"), for 5-7 years. Never cleaned the house, never did the lawn, never helped out financially. #2 is executor of the trust and he had to literally get #3 evicted and move in just to get the house into shape where a realtor would show it. #3 was caught stealing wrapped presents Mom had left for the grandkids.
Many of you will remember the post where I disclosed the pains of growing up as a functioning autistic. You can imagine the pain that added to the situation.
Oh well, he's disabled, on welfare, and I'm the other side of the country. I have a very loving wife who's put up for me for 25 years now and things are better but a lot of pain remains.
