Low quality communication is better than high quality solitude. One should live a good life. Although it is enviable to see others in pairs, don't make friends just to make friends. In this way, few friends are sincere. I don't have any friends now. When I stay at school, I will bring an mp3 player. When I have nothing to do alone, I can try to keep some diaries. When you feel lonely, it's better to write them out.
