We have know each other for 2 years, so I make sure you will hep me to learn your mother tounge right? 
Honesty, I have been learning this language for six months, but actually I can't listen and my writing is not nice at all, so I hope that you're ready to give me some advices to learn Vietnamese. 
I am looking forward to your letter
