What is going wrong? Something have been changed during the time going. I know my mum love me as usual. But these day, I feel hard to talk with her comfortably. It is easy to have a argue or something. I don't know how to say. The fact is just that I don't even want to talk with her. It is too hard to express my idea to her. I know I love her, but the air has already changed between us. I don't know what to do now.
