People always attach the importance to the promise, they hate people who break their promise. I remember once a time, my friend asked me to go to see the movie with her, I said yes without hesitation. But on that day, I forgot about the date, I just woke up late and then played computer games in my bedroom. My friends called me, she asked why did I disappear, I said I was sleeping at home, she became very angry, until then did I think about our date. I felt so sorry, I break my promise for the first time, I realize I did the very bad thing. Even though I apologized for many times, my friend was still angry with me. I learn the lesson, promise is very important, we must keep it, other people will see through our personality to decide what kind of person we are.
