Wrong Flight

Lately it's been raining like crazy every single day. In fact, I can count on one hand the number of days it's not been raining since I have gotten back to Australia. This makes me think that I have somehow gotten on a wrong flight (in one of my many connecting flights) and have ended up somewhere in the UK instead. For whatever reason, the UK also happen to have a house exactly like mine in Australia, with the same people, and the same neighbourhood. So tomorrow I'm getting on a flight to go back to the real Australia where it's supposed to be summer, full of sunshine, mozzies and stars.

Meanwhile I decided to go on the world wide web to search for the reasons behind this above average (to put it mildly) rainfall. Some people think that it's the La Nina effect: where the air surface pressure is lower than normal in western Pacific which allows warm water to elevate to the surface. With the evaporation of this warm water, clouds form and the trade winds blow these clouds all the way over to the east coast of Australia, causing torrential downpour. La Nina is the opposite effect of El Nino which is what some people say have caused the draught for the last couple of years. Anyways, instead of reading my bullshit, you should check out wiki yourselves.

With this, I would like to ask a question, why does everything have symmetries?
