It is strange how the romances of the teenage years retain a poignancy all through life - how a girl who turns you down when you're 16 retains an aura in your memory even long after you, and she, have ceased to be who you were then. I attended my high school reunion a couple of weeks ago and discovered, in the souvenir booklet assembled by the reunion committee, that one of the girls in my class had a crush on me all those years ago. I would have given a great deal to have had that information at the time.
