And they will prove it if you aren't on guard.

A story like this makes me think of back in the early 1980s, me and my Dad watched some program on Yellowstone and other U.S. national parks and people visiting them. In one part, they showed a campground and there were that good number of people sitting outside their tents or campers and watching TV and this, of course, would have been when TV sets were not the most easy things to pack up and take with you compared to nowadays. And it really struck me and my Dad about these people just sitting there watching TV like they were still in their living rooms at home, as opposed to simply being in the outdoors and enjoying the nearby area.
