It would upset me to not be able to tell my friends "Hey, I'll be out of contact for a while." but that's really not a problem unless something major happened. The rest of my family, however, is not quite as adaptable at being away from their computers or video games. My mother complains enough to be offline for ten minutes, so her withdrawal for a few days would be worse than going through my own, and the kids would do their own grumbling to be stuck reading, playing board games, or *gasps* GOING OUTSIDE TO PLAY.
Now getting enough hot water for everyone to bathe? No means of cooking at home, and likely restaurants being out too? That could be more problematic, but still less of an issue if people leave the fridge shut to keep as much cold in as possible. Not likely to happen with bored and hungry kids...
