and also, they are use to their own dialect ..
i use to laugh at my papa or mama when they 'try' to speak english. cause the way the pronounce words always sounds so funny. they would always jokingly say, 'mama dont know you never teach mama then how mama learn..' then one day, it suddenly struck me. hey, its this two not educated adults who sent me to school to study . not for them, i will be like them, kana laugh by other people ..
