No one has ever encountered new people in their lives who are a little different from what you are used to? I emphasize, not the opposite of yours, but different from yours.
So in other cases for me it is very informative, curious and even to some extent expands my facets. And I'm learning something new. Going beyond your own self, It makes me new, and often no worse than I was before.
It seems to me that partly because of this, people develop and move forward, and do not stand still.
Or maybe the ideals throughout life will be adjusted as a person grows? Do you agree?
