Who understands you?

I asked some of my friends who were/are in a relationship..as to what the crux of the start of their relation. Most of you should have easily guessed the answer by now -
"Oh! We understand each other on a totally different level. He/She understands me like no one does."

I have always thought about what makes this variety of "understanding" so special that only a single person qualifies it for the maximum score? There must be definitely something and that something surely lies in the way you understand or reach out to the other person. After a lot of grueling thought process,I found only 2?!

The first basic qualifier - You both think on the similar lines maximum times and you appreciate that person for what he/she thinks.
Second - Even when you don't think on similar lines, you put yourself in that person's shoes and then give your views. You don't make the person feel bad while doing all this..and manage to find a midway or a safe zone.
Bingo!..1 and 2..these are the basics.

If you fail to do even one of those, then let me tell you that the other person will always blame you for hurting his/her feelings.

Sometimes they will even tell you that your understanding is so damn minimal as compared what he/she shares with his/her friends. However much the people will claim that their friend or lover qualifies to the same standards of understanding, this comparison is ridiculous as there is a lot more pain involved in the 2nd case when the standard does not match up.

I have witnessed some broken relations with all the misunderstandings involved and really I would hate to see more of it...So, I am just blabbering here..
