There is no free lunch in the world. A 2000-word essay titled

Recently, my grandma went out at dawn, queuing up with a group of old ladies to get free medicines, various free gadgets, and listen to health lectures, which made her smile from ear to ear every day. I think there is no free lunch in the world.

That day, my grandma started talking again and again: "The person teaching us today is from the Elderly Care Group. The state invites them and gives them millions every year. His laptop bag is still It's genuine leather!" "Who can prove that what he said is true?" I interrupted my grandma. "He has a certificate from the country!"

Oh, naive grandma, there are so many fake people now, how do you know whether his certificate is true or false.

The next day, grandma came home from class. When she saw me, she raised the pearl necklace in her hand and said happily: "Here, look, this is a free lunch!"

I looked at this necklace carefully. Some of these pearls became pregnant women, some looked like conjoined twins, and some were scarred. It was almost impossible to find a perfect pearl. Seeing my grandma's triumphant attitude, I said unconvinced: "They must have a purpose to please you. There is no free lunch in the world, just wait and see!"

Sure enough, after a few days, Grandma came back and said: "Experts say that boiled water is not as nutritious as filtered water from drinking fountains. Today the experts showed us a drinking fountain. The original price was 10,000 yuan. We old people can buy it for only 5,000 yuan. We should sign up early." There are only twenty places." Grandma took out a bottle of water from her bag and called to everyone: "Come and try it, it's nutritious!"

Dad asked about a water dispenser. The ones produced by regular manufacturers only cost about 2,000 yuan. Grandma disagreed after hearing this: "There are only twenty places anyway, so I can't be ranked. I just won't buy them next time they sell something."

But grandma was still fooled. That day she came home carrying two cans of protein powder. There was no brand or manufacturer. When asked, the price was two hundred yuan! Grandma happily said to me: "This is buy one get one free. I managed to grab two cans and bought them just for you. Nowadays, foreign children have a cup of protein powder every morning, and milk has been eliminated. Experts say In China, only aristocrats and celebrities can drink protein powder. Children are very smart after drinking it!”

Looking at my grandma’s face with joy, I really couldn’t bear to say anything else. Kind grandma, there is no free lunch in the world!
