On January 1st, we got paid. I received 600 yuan, and my wife received 400 yuan, making a total of 1000 yuan. I solemnly recorded in our family's GDP ledger: On January 1st, GDP income was 1000 yuan.
On the 2nd, my son needed to pay 600 yuan for his school tuition, so I gave it to him. Then, I quickly noted in the ledger: On January 2nd, GDP income was 600 yuan.
On the 3rd, during dinner, my son accidentally kicked over the hot water bottle and broke it. I spent 20 yuan buying a new flask liner and installed it. Then I recorded in the ledger: On January 3rd, GDP income was 20 yuan. I then praised my son saying, "Good job! With that one kick, you've contributed nearly 1.5 percentage points to our family's GDP growth."
On the 4th, my son borrowed an extremely realistic toy tank from a classmate. Seeing it was fun, I wanted to play with it too. My son said, "If you want to play, it's 10 yuan per session." Normally, I wouldn't be willing to spend this 10 yuan, but thinking about contributing to the family GDP, I didn't hesitate and agreed, paying my son 10 yuan. After receiving the money, my wife said to my son, "You need to pay 2 yuan as personal income tax." Reluctantly, he handed over 2 yuan. So I proudly recorded in the ledger: On January 4th, GDP income was 22 yuan.
On the 8th, Sunday, the whole family went on a crazy shopping spree. We bought 100 pounds of rice for 170 yuan; a canister of gas for 70 yuan. After some thought and gritting my teeth, I bought myself a pack of cigarettes for 3 yuan; stomping my foot, I bought my wife a jar of Snowflake cream for 6 yuan; after much hesitation, I bought my son a string of candied haws for 1 yuan. Upon returning home, I hastily recorded in the ledger: On January 4th, GDP income was 250 yuan.
