Unlike many people, I speak Chinese as if I didn't have any knowledge of English.
In other words, I don't use a single word of English when I speak Chinese, not even "OK", "Thank you", "Hello", "Bye bye", "Yes" or "No".
Why should I when there are more than enough Chinese words and phrases for me to perfectly and precisely express what I want to say?

If you ever talk to me you'll find that I talk the talk and walk the walk.
