Question of the century.

How do people in the southern hemisphere deal with summer holidays?
Do you people have some kind of crazy, backwards winter holiday? Or do you have a summer holiday in december?

But that would mean that either
A. Your holidays coincide with cold and snowing. or
B. You're holidays clash with the christmas holidays.
In which case, do they cancle each other out or form some kind of malformed super holiday?

I need answers people!
