Diary Taday, I felt a bit unhappy. Before I write this diary, I think I should know something at first. Actually, I always know that in my heart. We treat someone else as a true friend with all of our kindness, it is voluntary. No one has a right to ask for a repay. I don't think I am a kind and self-giving people. Sometimes I will just think about myself. But I think it is normal, everybody will do it no just me.The premise is that I must not hurt other people. This afternoon, a friend, who really made me feel sad. I didn't think I have done something wrong to her. Compared with other friends in our life, I am not the best friend of her, at least I am a reliable people to her. However, the thing which happened today, I found she just thought about herself. She didn't care my feeling. Even though I tried to stay away from her intentional, she didn't care at all. She made me feel frustrated.
