At the age of 16, I spent 1 year in Belgium in 3 different families with Rotary.
I still visit my house families in Visé and have kept very good friends there. That's also where I learned to speak both French and English.
Later, I decided to go to South America to learn Spanish. My trip, initially planned to last 3 months, extended to 2 years in Buenos Aires. I have kept many friends there too, especially from Ecuador.
