I had to pick a orchid subject in high school and "computer science" sounded interesting - or everything else sounded less interesting.

That was the second year in which this subject was available. The year ended up with me teaching the teacher because he didn't get some things I was doing with Java. It was possibly dumb things but it worked.

Was a fun teacher most of the times but I think he had some kind of ego problem.

I got an A- because I spent the night before optimizing something and didn't test everything so something did indeed not work when he graded the program - a very simple room booking system. Fun times :)
