Halo, you're from FL right? Why not try someone in the US to start you off, and if you want someone overseas to write to, ask a language teacher at your school, they usually know good agencies.
I have a total of 12 overseas penpals, not including old friends from England and PT people! :D It's really rewarding to get to open your heart up to kids around the world, to experience different cultures!
Go for it Halo!
Reach high, for the stars lie hidden in your soul. Dream deep, for every dream preceeds that goal.
