Why do I feel guilty when men and women open a room! ?

First of all, it shows that you are a traditional, orthodox and noble person.

There are many possibilities for men and women to open a house, such as derailment, travel, business trip and so on.

Guilt comes from a common ideological pressure around us. In other words, traditional concepts have bound our ideological cognition.

Suppose you are in a foreign environment, you may change. This is because of the different environment and education, which leads to different thoughts and cognition. It's like holding a stick in the 1960s. At that time, holding hands directly was definitely considered guilty.

Our thoughts keep developing with the development of society.
