The twins don't bitch because they have been very well brought up by their parents. Bitching stems from self insecurity and the requirement to feel better than someone else. The twins also demonstrate that neither academic intelligence nor age have much to do with self confidence.
Bitching, and I don't mean arguing, is a highly negative and destructive force, and those that understand this just move away and avoid it very easily. If they can hold out through their bb experience they will certainly have my admiration.
