When I was in my last year in middle school, we had this hip young math teacher.

He used slides sometimes for his lessons, and some day we noticed a Street Fighter tab in his browser.
So a couple of friends and I decided to investigate and we found out his username. He was some kind of competitive SFII and IV player.

Last year I was talking with old friends, and somehow we brought up that subject, and looked for his username online.
We found out he's been playing a loli in FFXIV ever since he divorced. Truly a great man.
