Yes, not showing feelings, and keeping your temper was very much the scenario for my h and his sibs. His father had a vile temper, but generally both his mom and dad sulked if things weren't going well. The silences in teh family home were tangible!! But it can't have been any fun growing up there.
The idea of people talking things through was just so unthinkable to them . . . .So nobody talked about anything, and then occasionally there would be these huge scenes from his dad.
When the sibs get together they all have the weirdest body language. And emotionally they regress to about 16.
Have you read 'Silent Sons'? It is a revelation about the dynamics and effects of dysfunctional families - even teh denial that the family was dysfuntional is apparently fairly typical [though not invariable].
