Of course, we professional programmers never make mistakes, ahem. That’s why we never need to use debuggers, ahem.
Well suspend belief for a moment, and assume that I had a bug in the code I was developing. You know the feeling, you stare at it, you write unit tests, you stare at it some more, and still can’t work out why on earth Visual Studio is claiming that there is an error in your code, when it’s so obvious that there isn’t. You even get to the point of talking to your computer, pointing out the error of its ways.
Eventually, you spot the mistake. Once you’ve seen it, it was so blindingly obvious that you can only offer a silent prayer of thanks that no-one else was in the room at the time. You change that one tiny typo, and suddenly Visual Studio stops complaining about your code and it all runs correctly.
Just as you sit back relieved, you notice your computer smirking. I’m certain mine just laughed at me. It did it quietly, but I noticed. It hates me.
