ALT [0:05:59.5] KB: Okay. I thought, well I'll give a class on test-driven development, because here I am and I can – nobody’s using TBD, so well, of course, they'll want to learn from me. In the signup sheet, I went and checked just before I left. I went and checked the old, old wiki and the evidence is still there. The class just before mine on the list of classes was about advanced techniques in Excel and it was full and there was a waitlist. The class just after mine was on Argentinian tango and it was full and there was a waitlist. I had zero people sign up for my class. I thought, “How am I going to have any impact here, if people don't listen to me?” I deliberately chose to forget everything I knew about software engineering. I just said, “I'm going to try and be a programmer and I'm going to watch what people do. I'm just going to copy what they do. If somebody says this is too diff since that one, it will be too diffs. If somebody says you need tests for this, I'll write tests.
