Yes, the chinese never know when to stop at times do they?

I remember once many years back, some odious clerk at the school came a rapping on my front door of school provided flat at around 9:30 at night, he insisted I teach his friends kid english there and then, I just laughed and shut the door in his face, and changed the locks the next day, only problem with living in China I found, if you are a foreigner or like you with mixed child, they think they can invade your privacy relentlessly. Does get wearing eh?
