His name is FERDOWSI; he tried 30 years to verse SHAH-NAMEH. The great book that has not even one Arabic word! He saved us & we love him! If you can be a hero just start! & if you can’t, you better find a hero! We Iranian people are very happy that have ourselves mother language, this causes to feeling us... WE ARE!
2- "Learn it, even if it bothers you!" maybe they used you for giving a bad message, but even in this condition you must learn your mother language. A slogan of course with some irony and exaggeration!

4- "Spy better with your mother language!" one of the most applicable usage of mother language, of course with some irony and exaggeration!
