my brother \)^0^(/

Today, I would like to introduce a special person. Who graduated from Chenggone High School and now study at the same school and department with me. Recalling before, one day we went home together from our college. At first he told me he forgot his key so he must go to his uncle's home to get it. I could tell you if I wouldn't have gone with him, he haven't had known where his uncle's home is. Actually, I don't know where it is. But ,fortunately, the house is near mine. How could I know it? The reason is he told me the house is at the same MRT station with me so he could accompany with me to go home. As soon as we left the station, he was not sure which direction is correct. I told him thet the probability of that location direction was 90%. At least as we went a long time he remembered it. However, after that day, he told me he still took a mistake. The right place is the next road. The thing was his uncle told him. There are a lot of this kind of examples. Except those he is a not only kind but generrous person. He really cares about me. He also has a sense of humer and good temperament. Finally, what is our relationship? We are brother and sister. I am so lucky that he is my old brother-non-in-blood.
