Thầy Andry Thành thân mến,
I can write an English passage very long. Though its grammar wrong, but it made my friend shocked.
Now she is traveling with her family. I can't imagine what will happened when she comes back, when she hears me to speak english (previously i couldn't speak any English words :D) . That's a fantastic emotion I've today and i want to share with you.
You're right, positive emotions can make me believe that i can do everything. Hope you happy for my small story, Trainer!
