aaah!!! finally somebody contradicts~~hail thee Ealga-san!!!!! well...i think it all goes down to the gender roles that we consider to be normal according to the norms and values of our dear society...in fact, males are attributed the instrumental role, that is in simple terms, the hunter role...that means they have to be 'Males' à la Tarzan which means, virile, deprived of feelings and therefore not showing them...women, on the other hand are given the expressive role...which means that they are sensitive...again goes back to the gatherer role....so, women hugging is normal and men hugging seems gay...
as for the teamwork...erm...i'll find something someday..................definitely~~haha
