The word friend is defined in American English as aof affection or personal regard and esteem. In British English, it is defined as a person with whom one has a bond of mutual affection, typically one exclusive of sexual or family relations. Depending on how deep the bond or strong the attachment is between two persons friendship has been categorized from casual friends to close and best friends.
The value of every friendship, just like other basic things that we need in our life, can be categorized according to our need of it. I am always amazed at the fact that some people (if there are any) could sustain the level of friendship they have with another person from childhood. The reason for this is because when I look back to my friendship track record I can count in one hand the number of people I would actually call my friend or have been my friends at some point. Each one of them came on different times of my life, although there had been times that I had different friends at one time. I do not want to discount the value of each friendships that I had but no matter how hard I tried now the level of bond or attachment that I had with them is o longer the same. We still call each other friends but its just different now.
Friendships can be found even in the most unexpected circumstances. It does not matter whether the friendship has been there for decades or just a few days. They are all the same, beautiful friendships gives us wonderful memories to remember by and every honesty and truths shared with our friends provides us with lessons to live by.
All friendships are developed according to the trust and respect each person is willing to give to one another. Maintaining a certain level of friendship would be a matter of choice because each one of us has to lead different lives and build other relationships depending on our social or marital status. As we mature personalities and outlook in life changes and according to where we currently are we build new relationships including friendship.
Anyone can be my friend depending on whether the other person wants me to be her or his friend. Just like any other relationships, respect is a prerequisite to a beautiful friendship. Two people with different personalities can be close or even best of friends as long as they are willing to accept each individual unique differences and are willing to compromise at a certain point.
