A few (ahem) years back when I was in college, I encountered a fellow student who had a propensity to take things that did not belong to him. He just could not help it. He would see something he wanted, and the next thing you knew, he had it in his possession (much to the surprise of the former owner). He stole from strangers. He stole from friends. He stole from me. When I became suspicious of him, I set up a sting operation in my dorm room giving him an opportunity to prove me wrong. Unfortunately, he failed the test, but I had prepared for this possibility. I caught him red-handed and shame-faced.
