I think i know which girl you talked about, i met her for sometimes in 2004, she works as interpreter for many years, i believe she is rich, she dresses well and she bought a notebook PC cost more than 10,000rmb, and she has nice mobile and camera. so she owns those expensive things before she start to assist in that school. a motorcycle cost about 3000 rmb, i would not be surprise if she buy one. I think she doesn't need foreign students to pay for that.
And she is very smart and speaks good english, I don't believe that she would say such stupid words to people.
