We're you good at school?

I spent only 2.5 years in high school and I yet graduated a half year late, so you can guess that I basically hated every single minute of high school. There were so many other more interesting things to do in life. I had absolutely nothing in common with my school mates and most of the teachers were just 'doing their job' unenthusiastically. But I did get that gawd damned diploma, which I have never been asked to produce for any reason, in my entire life!
