one of my friends will leave shenzhen days later. she will go back to Xi'an where we live together and study together. one year ago,  we came to shenzhen toghther for our dreams. at the very begining, we lived in a samll room and slept on one bed. although we quarreled with each other for several times on different opinions,we even didn't talked to each other for a long time. but when i got the news that she will leave, I felt a little bit lost.sometimes, when i felt blue, Icalled her and we had a long chat, after that, I felt better and faced all the things I encountered with confidience and courage. she go back for her family and some one important in her life while  I have to stay here for unknown future .
