Dear Kate,
Today I discovered, over a lunch discussion with my colleagues, that one of the main reasons why I do not break the law is because it can be very hard work. All the effort spent scheming and plotting, when I can instead relax and just lower my threshold of contentment. And maybe the reason why we sometimes get indignant about other people who cheat their employers etc. is that we are jealous of their ingenuity and our own corresponding lack of imagination? I do hope of course that it's because we are good people and therefore abhor evil deeds :)
