I've heard of a Type A personality, but not a Type B. What is type B? I am definitely not Type A (the driven, aggressive, competitive personality). I am more laid back. Is that Type B? I don't see that it is related to my ADHD symptoms. I am not sure what you mean by "without getting to know them"? It seems like someone would be aware of your personality long before they became aware that you have ADHD.
