"Friendship has no expiry date".
This was part of a text message i received on my mobile phone, from a close friend.It set me thinking. Is it really true? Is a good friendship something that lasts forever and grows better with age? Many of us would have tales of how we have nurtured a friendship over a long period of time. But for each such special friendship that is spread over a decade or more, how many broken friendships are strewn along the path? Even people perceived as being very close to eachother have drifted apart/cant stand each other's presence.
My opinion on this is thus: Human beings always seek some gain in whatever they do. The gain need not always be something materialistic. The friends we make at any point in our life depend on our circumstances. Though one does not befriend someone having only ulterior motives( that is not friendship anyhow!), quite unconsciously almost all of us tend to be friends with people who will at some point of time be useful to us. We befriend those who share some common activity.So friends are mostly circumstantial. Once the common thread that held the friendship together, no longer exists or is no longer strong enough, the friends tend to drift apart i.e the friendship reaches its expiry date.
