It is very important to know about interpersonal relationships - What keeps them going...& what really disturbs them.
Interpersonal relationships get disturbed, when disagreement begins. As long as there is agreement, they don't get disturbed at all. So what disturbs a relationship? ... Disagreement.
Now take a look at yourself... Have you always agreed with yourself?
you have not agreed. You had an idea yesterday... and today, you have a different idea! Five years back you had different ideas and they did not necessarily agree with the ideas you have today. So when you can have a disagreement with yourself, why not with someone else, next to you? The person, with whom you have a disagreement, is just an old photocopy of your old self - or maybe even a new copy ! What you disagree with today, you may agree on, three years from now. So you need to take a look at your own thought patterns and your emotional patterns
