A few days ago, my aunt and I went to buy watermelons. We walked on the street and saw many watermelon stalls. My aunt led me to a watermelon stall. After knocking a few watermelons, I asked my aunt: "Aunt, if you buy watermelons, just buy watermelons. Why do you knock a few more times?" My aunt said, "I knock the watermelons to see if they are ripe." I asked my aunt again: "Auntie, how can you tell whether a watermelon is ripe or not?" Auntie said, "If the watermelon seems to be empty when you knock it, it means it is ripe." I said, "Auntie, why don't I take care of todays watermelon? Choose." My aunt said, "Okay." I liked a big watermelon. I knocked it with my hands. I felt that it was not empty inside. I continued to knock on the watermelon. When I hit the fifth watermelon, At that time, I felt it was empty, and I said, "Auntie, lets buy this watermelon." After my aunt paid the money, I took the watermelon back home with great effort. After returning home, my aunt cut the watermelon open. I found that the skin of the watermelon was made of dark green and light green beautiful wavy lines, the flesh of the watermelon was red, and the seeds were black.
The watermelon was cut, and I put it on the table. I took a big piece of watermelon to eat. I took a bite and felt it was very sweet. At this time, my uncle said, "Who is this watermelon?" Its so sweet." I said proudly, "Uncle, I picked this big watermelon. This is my first time picking a watermelon!" My uncle said, "Then you are really useful. You picked one the first time." Such a sweet watermelon."
After hearing what my uncle said, I was very happy.
