We all have them.
We all want others to side with our opinions.
Guess what? Not going to happen.
First of all, opinions are just that; opinions. They are not the deciding factor in relationships.
We all come from different walks of life, with different experiences and feelings about those encounters. So to persuade another to believe, feel, think, and do things the way that you want them to, is not right, good or fair.
Instead, try to understand where the other person is coming from; and where they are trying to go and get to.
The other person is not you.
That being said, this does not mean that relationships should change; maybe it could bring closeness and a soft place to fall for each of you.
Support, don't judge each other.
