今天家里什么好吃的都没有了，可我有点饿了，我叫妈妈给我买面包和牛奶。妈妈说：我给你20元钱，你自己去楼下小超市买东西，我在楼上窗口看着你。我就大着胆子下楼自己买了一个面包，一袋牛奶，我回家还给妈妈报了一下帐：我拿了20元，花了5元，还剩15元。
Today, there is nothing delicious at home, but I'm a little hungry. I asked my mother to buy me bread and milk. Mother said: I give you 20 yuan, you go downstairs to buy things in the small supermarket, I look at you in the upstairs window. I boldly went downstairs to buy a bread and a bag of milk. I went home and reported to my mother: I took 20 yuan, spent 5 yuan, and left 15 yuan.
就这样，我的胆子变大了，妈妈还表扬了，我真高兴啊！
In this way, my courage has grown, and my mother has praised me. I'm so happy!
