I have two foreign friends, Kari and Vance, and they come from the USA. Now they are teaching
English in the university in Nanjing. Last year they paid a visit to our school. I have never met any
foreigners before and wanted very much know that I was getting on with my spoken English. So I
went over to talk with him. All of them were surprising a school student could speak English so well.
They suggested to taking a photo together. Since then we had been good friends and now write
English letter to each other often.
