My father was using his notebook computer in the study room. My mother was also using the computer, but she was in the dining room. I was helping her in using the software of Chinese Plus 2004. The power supply went off suddenly and our flat was blackout.

My father and mother were initiately thinking that our power supply was overloaded. Looking out of the window, my father found that the street was also very dark. He said it was no power supply for our housing estate and not only our flat or our block.

The blackout was so sudden and we could not remember where we keep our torches. My father always put one torch near his pillow and one in his study room. But he could not see any thing at all.

I remembered that I have a bicycle lamp. I went to my bicycle and switched on the lamp. It gave some light. Therefore my father could look for his torch. I later remembered that I put a torch, which I brought to our school's adventure camp, in the living room. So we finally had three torches. I held one, and my father and mother also held one each.

I told my father that we should go out to see whether there was anybody in the lift. We did not hear any siren from the lift. We walked slowly to downstairs and found one of the lift was open.
