It's difficult to say goodbye

 Tomorow is the last day when we study in castleton university,it's also the last class in professor Philip and Karen. I am very sad to face that day. It's difficult to say goodbye for Philip, Karen, Erica, Devo, Shambo and Regan.Thanks for they took care of us and told much more American culture and language than we knew before. I also study too much from Erica, Devo,Shambo and Regan. They are kind, helpful,optimistic ect. It's very happy to talk with them. I believe that we also keep the comunication by the Wechat. And I aldo believe that we can meet in China or America in several days.
