Hello .   Mark , this is Lucy .   What's up ?   I have a friend . He is my best friend and he wants to learn English . He would pay about 100 yuan per hour . Are you interested ?   I don't know .   So I take it you are not interested .   No , Lucy . Don't get me wrong . I mean school will be open on Sept . 2nd , and I will have a very tight schedule by then .   Don't worry . My friend says he can always arrange his schedule around your schedule .
