First, I liked to collecting the cute dolls. So I was sleeping with my dolls or playing with my cuty dolls. But now, a piano is full of dolls in my house . I haven't played with my dolls nowadays. So I need to throw away. But I can't do that because there are a lot of memories of my childhood. Second, I need to throw away my middle and high school's uniform. They don't need to me no more and they just take up space. But, there are also a lot of memories of my childhood so I can't throw away.
