I used to believe adults who made the systems in the world were really thick in the head. Here are two reasons why:
a) The way a clock works. If you were going to have two of something, couldn't you have made it two dials, instead of two needles?! One dial with only the hours (numbers 1 to 12), one dial with only the minutes (numbers 1 to 60). My childhood brain was very stubborn and just couldn't accept that a 1 could be 5, 2 a 10 and 3 a 15 and so on. It was the dumbest instrument to be ever made; instead of being easy to read, it was totally frustrating for me.
b) Piano books. Please, I beg of you, why on earth did you have to start at different notes for the left hand and right hand? Couldn't you respect the beauties of nature, and mimic symmetry?! I ended up giving pinao for this very reason. To this day, I solemnly detest piano books; they make no visual sense to me at all.
