What is basically just a scrap of paper has somehow survived in the confines of one wallet after after another, since the 8th grade (I think?), when I was assigned America’s 9-digit number, the last 4 digits of which, like my mother’s maiden name and high school mascot, still must be summoned from memory several times a year. I sometimes get the last 4 digits of this confused with the last 4 digits of my phone number, or with an ATM card PIN. This looks like I used to think my last name was THOMAG. The “A” is for ALEXANDER, as in Alexander the Great, one of my mother’s heroes.
