Well, nobody else is posting. A few more memories:
>Second-ever con, I'm still a nervous shut-in who can barely talk to anyone
>End up in elevator alone with woman dressed as Chocolate from Sorcerer Hunters
>Desperately holding on to spaghetti
>"H-how are you liking the con?"
>"I'm having a great time!"
>Why does this woman sound so familiar?...oh shit it's Tiffany Grant
>Struggle to think of anything to say
>Asuka Langley Soryu tells me "this is my floor. Enjoy the con!"
>Manage a "you too" and feel like I just met a celebrity

Another time:
>Cowboy Bebop VA cast reunion panel
>Audience Q&A portion, everybody's asking pretty good questions about working on the show, voiceover in general, etc.
>Guy gets to mic, looks at Steve Blum and says "this is the stairway to heaven...ya know that, don't you?"
>Dead silence
>"Uh...what's your question?"
>Guy stammers that it's a line from Mushroom Samba
>Spike Spiegel sounds like a disappointed parent: "I'm sorry, I recorded those lines in 1999, I can't remember all of them anymore"
>300 people cringe in sympathy as dejected weeb goes back to his seat

Or back when ACEN had a karaoke suite:
>Sign up to sing "Rain" from Bebop
>Wait 40 minutes, organizer comes over and tells me they had to bump me
>Why
>Mary Elizabeth McGlynn gets up
>Julia from Cowboy Bebop stole my song, and she fucking nails it

I feel like you never run into VAs and anime creatives just shooting the shit or enjoying conventions anymore. Hell, pretty sure I saw Yoko Kanno rifling through merch at ACEN back in the early aughts.
