I don't mind doing this through pm, but as it seems to me to be relevant to the original post I'll start here...if I'm annoying the rest of you folk, let me know and we'll go private.
I took the concern to be that many couples have one person who likes to manage and the other who's more passive. The 'follower' in this scenario (more often the woman, not always) ends up not having to think things through herself, and even ends up not physically doing things herself as the other person does more than his share of gear setup and whatever. Without this practice in self-sufficiency, the more passive diver does not learn the skills as effectively.
While this dynamic can occur in any pair of people, many 'mate' couples have that kind of pattern firmly established already, so it's more commonly a problem. I certainly see that dynamic a lot in couples I see diving, particularly when the woman is less into the sport than the guy.
p.s. -- didn't sound like an attack to me; just a question
