Friendship is about constant attention. Long time of neglect will upset our friends. If we let nature take its course without taking any action, friendship will eventually wither, like a flower which has been left without caring for too much time.
Now it won’t be so hard to realize that friendship is not as easy as it may seem. It is like the reservoir, which will dry up if one doesn’t constantly pipe water into it. It is like the glass, which is fragile and needs careful attention. It is sometimes difficult to handle.
To conclude, friendship is a mutual spiritual assist. We get supported and helped while at the same time support and help our friends.
