I guess it would be a candle evening and probably play my DS untill the battery dies.

I remember I went babysitting a while ago and the power went out.
Before the father of the kids went to work he was lighting candles all over the place,
cause it was getting dark, and I told him: when you are done, I bet the lights will go back on.
And it happend muhaha XD

Usually I just do all my work that should be done ages ago. Revise for school. Or clean my room. Like REALLY clean it :p.
If I have no work to do then I read a book, do some sudoku crosswords or I just draw something in my sketchbook.
If I like the weather then I go for a walk.
You can do a lot of things, depending on what you like :).

Kill myself. No, not really. If it's nice outside, I'd go out and skateboard. Or I'd go to the club with friends all night then sleep all day since it'd be sorta dark without power anyways... Uhh. I seriously would just find anyway to leave the house without power. And if my friends are busy? Paint the wall and watch the paint dry...

I live an exciting life.

I do needle work. I can knit with very low light, and my husband and I have a great deal of board games. The last time I have a long power outage it was for about two weeks, and I ate out a lot, as my stove didn't work. I was recently married so I was more fun and "adventure like" than the pain in the butt, most people saw it as.
