Nonsense. I say this as the brother of four sisters (I have a brother too). Four sisters with very, very quick tempers. Family legend has it that one sister shoved another through a sheet of plate glass for wearing her socks. They didn't speak after that, despite sharing a room for several more years. 'Emotional expression' is all very well when it's soppy lovey-dovey stuff - when it's raging, grudge-holding hatred, perhaps a degree of repression is a positive thing.
Good for my mental health? Not really. I could never keep up with who wasn't speaking to whom in any particular hour. I spent my childhood looking for somewhere quiet to read. Or prematurely ending fractious games by hoiking the ball as far as possible and sloping off.
I'm the oldest: I got the blame for anything they did, and bore the brunt of classic hardline old-fashioned violent parenting. As each sibling appeared, the parents either wearily gave up or worked out where they'd gone wrong, and relaxed considerably, until the youngest had a life of ease and luxury. Bah!
Of course, we love each other dearly now. Now, that is, we don't see each other too often!
So today's Friday conundrum: what are the worst, and best, things your siblings ever did for you, and you for them? Do wish you had more or fewer (or any) siblings?
