I used to pass by his house every day and once, my curiosity urged me to knock on the door. That is when I found out his secret: he was a diligent, ambitious, enthusiastic person on the inside, though he kept up an appearance of a slow man wearing worn-out clothes.
At the first glance, passers-by may see him as a “crazy” man sporting the same clothes everyday, one who never steps out from his home. Neighbours may see him teaching French to people or teaching Vietnamese to foreign adults. He may be caught writing something in his balcony at midnight. People will never know what he writes at that time.
He has something special from the first sight. But what prompted me to feature him in my first documentary was not his strange appearance but the fact that he seemed to be even more interesting when one begins to understand more about him.
