What I Have Learned 我学到了什么

Last week, my mother had to visit my grandparents for two days, so she asked me to stay at home alone and took care of myself. I was very happy to promise her to take care of everything. I finally could live alone. So I slept very late and played computer games for a long time, when I felt hungry, I ordered the deliver food. When my mother came back, she was shocked that the house was in a mess. I knew that I couldn't take care of myself. 
上周，我妈妈要去看望我爷爷奶奶两天，所以她让我一个人呆在家里照顾好自己。我很高兴并答应她会照顾好一切的。我终于可以独自生活了。因此，我睡得很晚，也玩了很长时间的电脑游戏，饿的时候，我就点外卖。妈妈回来的时候，她非常的惊讶，因为房子乱七八糟。我知道我不能照顾好自己。
