What's the subject and body of your first email ever?

I can't remember that far back - it would have been over 40 years ago when I was an undergrad. We had an email system on the university's IBM mainframe and on the CS department's Unix system (a PDP-11). When I got to grad school a few years later, I had access to email on Arpanet (the precursor of today's internet).

I had a leaf-node in a UUCP tree back around 1991. I have no idea what that email contained.
