I've known athenian_abroad since Fall of 1981, making him not just the LJ friend I've known the longest, but my second-oldest active friendship. Our mutual friend Nick is my oldest active friend, dating back to the 1978-79 school year, when we were in the 8th grade.

There's one female friend who I've known longer, but although we're still friendly and connected on Facebook, we're not in regular personal contact.
