I learned english when I was 5 years old and in my childhood I practiced it a lot because of two things: tge first one was my mom because she's an english professor and the second reason was because I studied in a bilingual school since I was 5 years old until 15 years old.

When I was 15 years I changed school and I started my senior high school in a public school and the level of english wasn't good so I used to get bored in class because of the level.

In 2013 I made and exchange year in France so now I can express myself in 3 languages.

I'll want to be trilingual so I'll practice more my english and my french.

I'll start practicing english because I'm a little bit afraid of lossing a language that I've practiced for a long time.
