Having friends is itself a boon,for all.You would like to have friends,from all ages,both sexes,always.If having friends is a boon,retaining friends,permanently,is another boon.
For retaining friends,one must keep in touch with friends,in their happiness,unhappiness,sorrow,grief.Then only the friendship lasts,long.
Friendship is really a wonderful feeling,where each friend likes to share his/her feelings,openly,intimately,take advice.
In my life I have been able to see friends,remain together,in their thick and thin stages.In fact they are refered as good friends.
One may have a friend from childhood,to death.But,what a joint effort is put by both friends,to retain their friendship,at all stages of life.That is real friendship.In these days,if one comes across such friendship,is it not worth celebrating?
So,make friends & retain friends,permanently.
