Why are mice not afraid of people?

People are evolving, so are animals. Rats are not afraid to see many people.

First of all, mice are not born afraid of people. It is only subconsciously afraid of an unknown creature many times bigger than itself, but if it lives with this creature for a long time, it will gradually understand his living habits or realize that human beings are not as dangerous as they think, so it will have the courage to swim in front of people.

Secondly, in the old society, people were much poorer, people did not have enough to eat, and mice did not have enough to eat. So once you find mice, you try your best to drive them away, so mice will be more afraid of people.

Now the material life of every household has made a qualitative leap. The mice at home are well fed and pampered. Many people are more afraid of mice than mice. If you don't say that you are full, you will be awed, and the mouse will naturally become more and more grandfather.
