When we communicate and we don't feel seen - we may tend to intensify and overemphasize certain aspects. We identify stronger with them which makes them seem insurmountable and unchangeable. This is when we try to prove something.
Know who you are but don't fall into the trap of clinging onto a certain self-image. Let's keep an open mind. There is nothing to prove because truth cannot be changed. When there is nothing to defend, there is nothing to lose.
