Those of you in the southern hemisphere....

This is not pregnancy related but I don't personally know anyone who lives in the southern hemisphere (I live in the US) and I've always been curious about this! In the northern hemisphere Christmas takes place in the winter. We decorate with snowmen, icicles, snowflakes, penguins, etc. All things cold and snowy! And sing songs such as Let it Snow, White Christmas, and Baby it's Cold Outside. But I know in the southern hemisphere December 25th is during the summer. Do you still decorate with snowy scenes? Is that associated with Christmas everywhere or just the places where Christmas takes place during winter?
