it was certainly an embarrassing moment at the time, but I had gotten perfect scores on all my coding assignments in school, so I expected similar on my first performance review. also, when we did evaluations of our professors at the end of each semester, they would always explain that anything less than a 5/5 was basically fucking them over and we better have a good reason for the rating.

it's hard to understand what a rating out of five actually means unless someone takes the time to explain it in plain english.
