What is your friend lifespan?
You might ask what a friend lifespan is?
It is how long you remain in friendship with someone until you drift way from each other for whatever reason. Some people remain friends for a lifetime, but some do drift apart.

You are no longer friends with your high school friend.
You may not even remember the friend you met during your internship.
As we grow older, we move from one place to another, we change colleges, work places and we keep meeting new people replenishing those we leave behind.

So who is your best friend?
Is your best friend from high school with whom you shared your best kept secrets, still your best friend?
Or has he also drifted since you moved away from your city after your first full time job.
Perhaps your girlfriend is your best friend now.
Girls usually are good at keeping up with old friends, and they usually make friends for life, and they even share their Boyfriend's secrets with their best friends, but for a guy, usually his drinking partners become his closest friends.

But they say that 'Old is Gold', and never to be sold, usually your childhood friends and high school friends are the only friends you will ever have for your lifetime. You colleagues, your drinking buddies, and club buddies will come and go, but when you are in need of help, your old friends will stand by you. Even if you call your high school best friend after 15 years of not calling, and ask for a favor he will most probably oblige. He might not even think that you are calling after 15 years, and that is for asking a favor.

He will feel so good hearing your voice that he would do anything to help you. Then, why did we forget them. Why do we forget to call him on his birthday, or his marriage anniversary. However short our friend lifespan would be for new friends, we should always try to keep in touch with our old friends.

A small gesture of remembrance, a greeting card in Christmas, a random invitation card for a ceremony , calling him on his birthday, letting him know of your promotion, of your childbirth etc will go a long way in nurturing your friendship.

And this we should do with all our new found and drifted away friends as well. Just as you drifted away from him, there must be tens of other people drifted away from him, but he will remember the one who remembers him. Who knows, he might become your best friend?
