I would have been ahead of my time

I went to the library near my office today to apply for a library card (I am not a resident of the county in which I work, although I used to be.) The clerk at the desk asked whether I had ever had a card from this county. "I used to," I replied, "but it's been a very long time." "How long ago?" he asked. "Um...before I was married, so at least eleven years." Upon further thought, I realized it was even longer, more like 20 years. The guy checked the system under my maiden name, and did not find me in the system. Since I was not in the computer, he entered my information and began my process. "What was your PIN?" the clerk asked. "Excuse me?" I responded. "What PIN did you have in the system when you had a card before?" he said, with some exasperation. Yeah, I had an online personal identification number for an electronic library system in the mid-80's. You know, before any of us knew what the Internet was.
