Why are you so stiff when you take the elevator? How can it be alleviated?

Personally, I think this has something to do with the narrow elevator space. Ignoring the elevator, if a person talks to you when he is particularly close to you, you will inevitably feel stiff and subconsciously want to distance yourself from this person. And everyone in the elevator is very close, so close that you have this sense of distance, of course, you will feel stiff. Moreover, the elevator is surrounded by metal, which increases the sense of depression in the atmosphere and makes people even more reluctant to talk. You can try. When there are only you and your friends in the elevator, you may talk. When there are many people in the elevator (especially when there are many strangers), it is difficult to communicate with friends.
