If we just take a glance at our dictionary – old or advanced – the meaning of friendship remains the same. “A friendship is a feeling which exists between friends”. In this sense, a neighbor can be a friend. Friendship can also exist between colleagues, school-mates, club members, extra, extra.
Here in our society, we have heard a great deal about best friends of the same sex. We have also heard a lot about friendship with fraternal affection. But much to my regret, almost nobody seems to be interested in the so-called “pure friendship” between a man and a woman.
