我的错误 My Fault 在朋友打电话来的时候

我必须做一些事情来弥补我的错。

在朋友打电话来的时候，并且呆在家里看电视剧。我很开心地答应了。但是那天到来的时候，我突然想起了我们的约定，我的朋友叫我和他一起去公园，我忘记了我们的约定，

　　Last week, my friend asked me to go to the park with him, I was so happy to say yes. But when that day came, I forgot about our date, I overslept and then stayed at home, watching the TV series. When my friend called me, I suddenly thought of our date, I was so sorry, it is my fault. I must take some action to make up my fault.

　　上周，我很抱歉，我睡过头了，那是我的错误。
