Here is a very interesting interview with a cheater. (Mild language warning on link)
One of the comments says
“A thief believes everyone steals.” A cheater believes everyone cheats
This is so true. When I was in Boy Scouts there was this one guy who always stole everyone’s food on camping trips. We will call him Larry.
There was one week long trip where we set up a base camp, and then back-packed in further for a couple days. Since the backpack trip was shorter you were only to bring what you needed. Well, Larry decided to take all his supplies since he didn’t trust anyone. We all figured our food was safe since Larry was going on the hike. Well, Larry‘s pack weighed a whole lot more then everyone elses, so he whined, moaned, cried and complained the whole time. The Scout Master ended up carrying his pack for him.
When we got to our camp Larry‘s solution was to eat all his food so he wouldn’t have to carry it back out. Then he starved the rest of the week. It was really funny. I doubt think he learned his lesson though.
