since before i could read. i got onto it through watching my sister play neopets and she taught me how to use that site. then she taught me how to play city of heroes and i pretty much grew up on that game.
fun story, but when i and my sister were really little, my dad taught us how to tell when his buffs were wearing off in everquest. when he was in a fight and we were sitting in his lap watching, we would tell him when his buffs were going down. i also learned how to log onto his computer by watching him type the password in every morning.
