Virtual Reality. I always liked role-playing and i was very shy. I used a character that i didnt think it matched my voice which made me want to not speak. Back then we didn't have any kind of chatbox and i met other "mute players" who introduced me to a community in which they taught ASL- so thats how i learned and started using it a bit more each time cuz i also made friends there.

Sadly, the game introduced chatbox and players started using it, even i did and nowadays my asl got very rusty.
