I remember when my brother was a kid, about 4 years old, and he used to call every boy he met his friend. Now he is older and he isn't looking for a friend anymore. His priorities changed. He has to go to school, attend after-school activities, do homework... . There is no space for a true friend. The same happens to adults who live their lives fast and carelessly. I mean the modern world forces us to care about material goods instead of spiritual, and that's why we underestimate friendship, which in our world should be a number one priority. Generally speaking, it's crucial to have a person with whom you can share your problems, spend time, be yourself and forget about work, debts, daily life troubles.. .
Admittedly, it is difficult to maintain a lifelong friendship. Usually we have friends at school, but then we choose different universities, move to other cities or countries and the relationship between two people vanishes. Moreover, friendship is very time consuming and nowadays we are complaining about the lack of time. We should reserve a few hours in week just for talking or meeting with friends. Anyway the in modern world we keep forgetting that friendship is not all taking but also giving, we are not costumers in a shop who are just taking products from shelves. We have to be prepared to help our friend when he will be in need.
I reckon that the recipe for life long friendship should contain ingredients such us: time for the other person, being open and understanding and willingness to keep in touch.
C.S.Lewis said that “Friendship is unnecessary, like philosophy, like art... It has no survival value; rather it is one of those things that give value to survival”. I think that these words couldn't be more
