Hi, Mary, I'm Stephen. I called you at 2.15 this afternoon, but you were not in. So I leave<br />a message for you. Some of our classmates and I are going to Mount Lianhua in Panu District<br />tomorrow. We hope you can join us. We will meet at the school gate at 8 o'clock in the morning<br />and go there by bus. We'll get there at about 9.30 a.m. If you want to go with us, please call me<br />back before 10 o'clock this evening. I'm looking forward to your reply.
