a person I am familiar with

The person I am most familiar with is my mother. Although she is not very beautiful, she has a noble character.
I remember one Saturday morning, my mother took me to a taxi to go to school. When I arrived at the school, my mother didn’t have any change, and gave the taxi driver 100 yuan. The taxi driver recovered two 20 yuan and one 50 yuan. Because of the hurry, my mother put the money in the bag without looking at it. At noon, my mother took out the taxi driver in the morning and asked her for 50 yuan to buy me a lunch. Suddenly, my mother was surprised to find that this was a counterfeit currency. I suddenly stupid, and quickly comforted my mother and said: "It doesn't matter, we can spend this money." Mom said: "We can't pass on our losses to others." I am not convinced: "That is not to let Did someone else hang us?” Mom stopped for a while and patiently said: “If you know that the money is fake, let’s go and use it, it violates the national decree. Although the counterfeit money has caused us losses, we can’t go. To do something illegal, you can't lose your conscience because of money, lose your personality, and be a person who doesn't speak morality." After listening to my mother's words, I shyly bowed my head.
I am proud and proud of having such a good mother!
