I was a foreign exchange student coming up on 3 years ago, and, one of the girls I made friends with (we both went thru the same private company to find us host parents) was a complete kelpto! I didn't realize it until half way thru the year, she finally told me, and the thing that killed me is that her dad was a doctor and could afford anything she wanted! She almost got caught once when we were in London, some guards came and took her as we were all walking out of a grocery store (found out later she stole vodka) but, they nabbed her for buying alcohol underage (finally let her go, w/ alcohol in hand, they released her in exchange for her phone number). I was scared for myself as well, I had no idea she had taken anything, she told us later, and I could have been guilty be association! I tried to avoid hanging out with her after that incident, but, it just shows that it's not just people who can't afford things, it the people that can afford things that steal too!
