In my house feel around for the flashlight or a lighter.
I actually went through this at work a few months ago. The whole town lost power in the middle of the night. And though businesses are suppose to have emergency lights, the place I work at had just upgraded the lighting system and wouldn't you know it? They forgot to reconnect them. So when it went out it was D A R K. I couldn't even see an inch in front of me. Me and the other 3 workers at that machine had to just stand there until a maintenance guy showed up with a flashlight.
