What were you like when you started playing Pokemon, /vp/? Do you have any documentation, like, videos you made when you were younger? Maybe old family films or whatever. Only thing I could find was a recording from Diamond which I posted on some forum, nothing special as it didn't have my whiny as hell voice.
