Well if the power doesn't come back on within a minute or two so that I can just go back to using my Xbox/laptop I usually just use my phone for accessing the internet until the power comes back on. If my phone dies before the power comes back on then I read. If it's been about two or so hours since I started reading then I'm just going to stop and go to bed and nap/sleep because there's fuck all else I can do after that point.
