Honestly? No, never in my life have I sent fan mail to anyone. I don't know, I was always the kid who just thought in regards to celebrities in general: "they're people and they probably get tons of fan mail every day....most of it probably doesn't get read or probably gets thrown away depending on the person and their ego...why bother? Why bother writing something friendly that they probably hear every day in thousands of other letters?"
That and I just didn't have much celebrity worship in me anyways. I respect a number of people like Yu Suzuki for example and if the day ever came that I should meet him then I'd be tickled pink like anyone else....but no, never did the fan mail thing.
For instance, I've met a few people who have a name for themselves. I met Director Shusuke Kaneko (Death Note, Gamera, GMK) through a friend of mine in a pretty casual setting at a bar. My mutual friend was actually surprised by my almost non plussed reaction. Even asking me "you knew who that was right?" as Kaneko left and I simply replied "yeah, I know...I was geeking out on the inside but didn't think he'd appreciate me geeking out loud so I played it cool." I don't know...I'm weird like that with my fandoms. It takes a lot to get me to show "outward passion" even though I do have it for certain things. I just feel silly geeking out in front of people. That whole "you should act your age" thing.
I was a very logical kid who was dominated by his "that's stupid" voice all too often. But no, I've never sent fan mail to anyone I've ever been a fan of,
