When I was 14, I was criticized by one of my coaches for being a dilettante.
I signed up for a summer camp, where he was a counselor. Thinking I would love it and stay for 12 weeks, I cut that arduous tour of play down to a measly two weeks, to his chagrin, and impoverishment. (I think he was on a commission pay plan at the camp!)
I went out for a number of sports, he supported that, but my practice time was cut by the operetta in which, suddenly, I had a leading role.
Who knew I could sing?
Anyway, on a remote Native American village basketball court in New Mexico, he chastised me for being a flake.
