I found the below e-mail from a reader kind of touching, and kind of disturbing as well — bothersomely realistic. See what you think:

My cousin Shabtai has been known to wear a suit and tie on Purim, the Jewish holiday when people wear costumes. When queried about his “costume,” he says that he’s going as a serial killer because they look like everybody else.
When my son, my only son, whom I love, was a little boy, he asked me, “Abba, are there really monsters?” I told him, “Yes, but they look just like regular people.”
