Why is it?

Because you're missing each other. The time you're away each other are filled up because of that chance of meeting.

Because both of you had known each other for so long. It had come to a point that both of you are now comfortable with each other. No more pretending, no more wearing masks. You're just being you.

Good friends are really fun to be with especially if we know them for such a long time. It's really make us feel comfortable and happy to be with them. Glad that you have that kind of friend

I think it is a psychological factor.

This post is perfect to me right now. I had this friend and we were friends at one time and then lost touch and she came on facebook and we reconnected and then it did not go well so I wrote her something and she finally answered today and I said that she did not want to fight for her friendship. I am not sad because people come into our lives for a reason and can leave for a reason also and she left my life.

Your best friend know many things about you and she was always been there for you. You both go out together, talk about many things (mostly are common to each of you). She is someone you really trust, too. Being contented and happy to be with her is something valuable. I have the same feeling with my best friends. I feel calm and relax when we are together.

Why is that so? It's because we can tell a friend our secret, sadness, happiness, sorrows,joys. They always sympathize us.They always comfort us.

Its just because of trust and best friends are like diamond and i don't have to make you understand the happiness of getting a diamond.
