Hi Solo and your brother!
I have 4 adult kids: oldest is 38, then 35,31,29. They have discussed the very same thing as you and your brother have. They feel that they learned what they don't want to get involved in and would never want their kids to experience that sort of life. They want their kids to be able to make their own choices. They all are successful in their careers and of course have all made bad choices at one time or another. Don't we all? They all still have issues that they deal with after being raised w/the JW mindset. The mind control was incredible and the hypocrisy rampant. But they have moved on and made good friends and enjoy life's pleasures.
I know I as their parent wish I could have a "do over", but that's impossible. Now we get together for gatherings and I enjoy these occasions that I missed w/them as they grew up.
Best to you both. I know that you will find a lot of people at this forum to help answer your questions. There is a lot of humor also.
