I grew up with my mother and my aunt, both of whom were moderately heavy drinkers. They both were fully functional, and did not come home and get drunk or anything, but they seemed to need a few glasses of wine every single day in the late afternoon until bed time. Then when I was 13, my uncle came to stay with us, and he was a full-blown alcoholic and addict. He would buy alcohol, and drink til the bottle was empty, and pass out. Sometimes on the sidewalk before he'd make it back to the house, and the paramedics had to come get him. He'd search the house for old prescription drugs, and take them. I was on Ritalin at the time, and he got the whole newly-filled bottle and took the whole thing. Not sure if related, but he had a heart attack later that week. Survived, but it didn't teach him a thing about his lifestyle. I never had friends over (in fact I had no friends my age anyway)... I would always go visit my adult friends at their houses or businesses. But if I had been NT, and had friends my age, I'd have felt weird not being able to have any over at our house due to shame and humiliation. I think it made me rebel from the family's acceptance of alcohol, and caused me not to want to get involved in that kind of activity. And I didn't. I can remember feeling like I was living in Hell, when I already was "that weird kid", and now I had an uncle who would get on hallucinogenics, and do things like decide that there were demons living in the ironing board, ripped it out of the wall, and carried it out into the middle of a busy street and set it on fire to kill the demons. Not long after that episode, he had to get locked up in the Illinois State Hospital.
