I use 80% English ,12% French , 3% Arabic (my native language ) , 2% German , 3% Smiley’s :p .
As I talk usually with foreigners, English is suitable for both of us .but if he’s a French-speaker I use English at first, and then French if he isn’t good enough in English.
Arabic is rarely used, because I use it just while speaking with a classmate or a relative.
Germans, is seldom used because of my limited skills .but, in future I’ll work more seriously on it .
Thanks for the question fireflytech .
