Long time no see

I am the oldest child in my family, and I have only a younger brother. I have had good relationship with him; for example, we could share interesting or bad things that happened in the school. Sometimes we told about secretes each other. However, we have hadn't gotten along for a long time since he entered the collage. Now he is studying in a National University of Kaohsiung. Although it is not far away from our home, he can't often go home and get together with family. The reason why is that he always busy at the schoolwork, tests and Guitar Club. To this day, I have hadn't seen him for three months, and I have missed him very much.
