To teacher: this lesson Andy have many times wait for you about serial minutes, in order not to loudly speak many times ,actually Andy speak one word above three times e.g for "straight"this word, and next can happened like this, but as the same time get 3messages remote Andy speak loudly by message,but Andy can't read clearly, such as like this will delay lesson time.we hope can dialogue by voice first and then to make him hear teacher's words not only wait be quietly by himself, hope later Andy work hard to study more and well.thanks!
