When I met my wife, she was working in the emergency department at UMMC and one of her responsibilities was calling people and letting them know their STD test results. You would be amazed at the volume of people who do not understand cause-and-effect. I think she had an older lady who claimed she got something from using the same toilet as a trashy younger relative, she had people who learned of the unfaithfulness of their partners, and then there was just the people who couldn't follow the line from A to B. The funniest thing was how it was like clockwork, if there was a rainy day a certain number of days later there would be a spike in people coming in for tests. Got nothing better to do, I guess.
