Speaking English in Xi'an

Put infront of a group of 10 chinese students, all with pretty good english that seemed to refuse to talk for about half an hour. Ok mild exaggeration but come break time and everyone comes up and starts talking to me... where were you 10 minutes ago. After that it livened up quite a lot but I am very greatful for Ped - (teacher volunteering over here doing a similar job) who I am going to exchange ideas for lessons with. I have been offered a guided tour of Xi'an so I can't be doing too badly (even if I did have to go back and add an extra o to the to i just typed).
