I Don't Keep My Words 我失信了

Last night, my friends and I made the plan to go out for fun. But early in the morning, I was too tired and couldn’t wake up. So I lied to my friends. I toldl them I was not feeling well, so they came to see me. I felt so bad to break my words. I decided to be honest to them. Since then, I will always keep my words. 
昨晚，我和我的朋友们越好了第二天出去玩。但早上的时候我实在太困了，起不了床，所以我欺骗了我的朋友。我告诉他们我不舒服，之后他们来看望我。失信让我感到很糟糕，我决定说实话。从那时起，我总会遵守自己的诺言。
