It's curious that Higor and I have known each other since we were 17, and we met exactly because of English language! But no, we didn't study English in the same classroom nor worked together as teachers, I mean, we actually studied in the same school, but in different branches. How did we meet? We were pen-pals! Yes, in a time where e-mail was not that popular, we did exchange letters! Guess we're getting old...
