If you would like something else to feel sad about, here is my story ...
We were all taught to play the recorder at school. I picked it up much quicker than the other boys in my class so the music teacher took me to one side and told me that he thought I had an aptitude for music. If I wanted to learn a 'more sophisticated instrument' then the school would supply it, and would also arrange for me to have free lessons. I quite fancied learning to play the piano, but felt that I had enough on my plate studying for 9 O-levels so I turned down the offer. The second choice boy had piano lessons instead of me. About 10 years later, I was in a music shop and spotted him demonstrating pianos and electronic organs. His playing was very impressive and it suddenly struck me that I had made the wrong decision 10 years earlier ...
