A friend has three children, two older girls, and a son, who is 13. She was joking yesterday that she wondered when her son’s voice was going to change because he gets mad when she confuses his voice with that of one of the girls. I’m not certain I reassured her when I said, “I think I was 35. I know that sounds bad, but I was really bummed because they threw me out of the boys choir just when I was starting to get solos.”
