Mate anyone who comes from a big family is going to carry on like a f**kwit compared to people from smaller families. It's all about your first exposure to social dynamics.
The good thing is that when people come from the third world (where you have to have big families for security) to somewhere like Oz, within two or three generations they're having small families themselves.
The ancestors of Anglo-Australians used to have big families too. Hell, less than 100 years ago we had 'the Catholics' who were considered loud, rude and violent, and had big families too. How many Catholic families these days have more than two kids?
Everyone fits in eventually.
No that is the biggest generalization I have ever heard.
I know people who came from families in Egypt that have a history of having two children, aunties and uncles all have just two children, grandmother etc as far back as they can remember going from Egypt until even after they moved to Australia.
Also I have multiple aunties in Australia who have had 6-7 children each and none less then four on my father side. While it is no longer financially viable to have 10+ children as it was in Lebanon 50 years ago they obviously still enjoy popping them out. Also my two aunties that stayed in Lebanon had 5 and 4 children respectively just to show that having 10+ children is not financially viable there either anymore and it wasn't purely location.
So sorry Pou your struggling!
