Social norms

In our last psych tute today we were talking about social norms.. and there was this one which refered to making friends..
Basically, in Australia supposedly people are more blunt, and when they meet someone they will be more willing to share deeply and openly about stuff than people in Canada do - they are very polite to each other and work on building up the relationship before they expose themselves more..
interesting.. so which one am I, I wonder?
I think I alternate hehe.. since Chinese culture.. I think are the type that keep to themselves more..? but then I've found that international students who are from that type of background tend to share heaps with another international student when they come to australia.. so i dunno..
nice to investigate :P
