"What do you think people did back before they had electricity or running water?"
Situation :
You want to take your family camping. They've never been camping before, so your daughter is worried about how she'll be able to shower and use the bathroom. She's horrified to hear that there are no bathrooms at the campground, but you think it's silly for her to worry so much about it. You ask this.
