Earth hour

Well, today 8.30pm - 9.30pm is earth hour as everybody know that (you should know ) which majority people will switch off their lights during that time. But how many people will do it? For me, I think 70% of people in earth will do so including me o.O. So are you guys going to switch off your lights too?? If possible, just switch them off, it's just 1 hour it isn't that long. Okay i gtg tuition (the thing that nobody likes !!)
