I think we all showed a great deal of love for him and each other. I didn't learn about the awful things he said about my mother until years later. He knew better than to lie to me about shared experiences.
But he did lie to me about other things. My Dad grew up in the Depression and served around 6 or 7 years in the Army Air Corps during WWII. My mother went back to work in order to pay for him to go to college. He was dearly loved by all of us. But gradually it wasn't enough for him. He believes he's smarter than everybody. I know this sounds like I'm bitter, but eventually he just wore me out.
I worked DOD and had a Security Clearance. He would show up at my apartment when I was single and announce he had weed and just assumed he could smoke at my apartment. I flat told him no, for me there was no ambiguity, in 1978 you could lose your job just having weed at your home. He was pissed, and apparently never forgave me.
I just wanted it to stay away from me, he could use all the stuff he wished. It wasn't enough for him, he was 21 and I was 28, he had no job and I supported myself and my son. The only way I could have kept him happy was by smoking weed with him. I wouldn't do it. Most people understand and respect others choices, not the narcissist, he was offended personally and I can only guess he thought I was disrespectful.
Things like that festered with my brother, he sabotaged me in numerous ways, I'd have to type 50 pages to go over all of it. I'm not embarrassed about any of it, but just conjuring up these spare moments of a brother-sister relationship, it kinda makes my chest ache.
