How to write a diary of going to the supermarket to buy food in 30 words?

At noon today, my mother and I went to the supermarket in our community to buy food.

The two of us bought a lot of dishes in the supermarket, except a dish that looks like Chinese cabbage, tofu, tomatoes and noodles, and finally bought some meat. Later, my mother asked me to take these dishes to the supermarket aunt for weighing. The aunt who weighed them thought it was a bit strange that I went shopping alone, so she asked me if I went shopping alone. I said, "No, I came with my mother. My mother asked me to weigh it."

My mother and I went home after buying vegetables. When we were washing our hands, dad shouted in the kitchen, "What did you buy?" Mother said, "I bought Chinese cabbage." Dad smiled: "You didn't buy Chinese cabbage, but mustard tuber." Mom said, "Oh, I thought it was Chinese cabbage."

My father told me and my mother about the difference between cabbage and mustard, and now my mother and I finally know what cabbage and mustard are.
