How should I write 100 in the diary of people who go shopping in wanda plaza?

There are many firsts in life, but the scene of shopping for the first time makes me remember it vividly.

One day, my mother gave me 50 yuan money to buy a basketball and a bar of chocolate in Wen Jing supermarket. Before leaving, my mother said, "Remember to look at the cars on the road and what to buy." I said excitedly, "Don't worry, mom, I'll remember."

When I arrived at Wen Jing Supermarket, I couldn't find my way. Just running around and looking everywhere, I still can't find basketball and chocolate. I asked the waiter wearily, "Where is the basketball?" A waiter said kindly, "wherever you go, where you turn, where you go, you will see." Because the waiter said east, west, north and south, I just took two steps forward and turned my head and said shyly, "I don't know where the east, west, north and south are?" The waiter asked strangely again, "little friend, you are so old and don't know the direction?" The waiter said with a smile, "Go wherever you go, turn where you go, and then you can find the sports area wherever you go." I went to the sports area to get the basketball as instructed. I know where the chocolate is, so I hurried to get it.

When I checked out, I was worried that the computer would be miscalculated or broken, and there was no change, but my worry did not happen. Because I gave the waiter 50 yuan money, basketball 30 yuan, chocolate 15 yuan, and found me 5 yuan.

On the way, I don't know if my mother will praise me when I get home. Where are dad and sister?

After that, I seem to have grown up a lot and realized my mother's hard work. I'll definitely help my mother buy things next time.
