I still encounter this as a grown adult. I'm working through a course on a programming framework I'm unfamiliar with right now, and several times have gone through a half-hour setup to encounter "Now that I've shown you the awful way to do this, here's a built-in way that's far simpler and less error-prone!" Extremely irritating.
