I have a friend. She is a charming girl and everybody likes to talk with her. In fact, she is a homely look girl but she smiles all the time. That’s why people like to stay with her. I ask her how could she look so happy all the time. She tells me that she wouldn't remember bad things for a long period. When she felt bad, she will choose to think about the happy hours. I realize the way to seeing things decides our mood. Life is short, while most people are stuck in few sad things and ignore the most happy hours. So I choose to remember the happy time and live the easy life.
