Having many friends and having few friends is obviously thinking of the amount of friends without caring much about quality. It's good to have few friends, but to have true friends.
It is always preferable to have quality friendships. Friendships built on trust, caring, love, understanding and reciprocity. A friendship between two people is between two people, never a single part. It has to have both parts. It must be a friendship strengthened in personal, intimate, and deep knowledge, to the point of this friendship overcoming difficulties, confusion, misunderstandings, quarrels, everything. This kind of friendship is built with quality. And nowadays few people possess those characteristics or are willing to acquire them. That is why friendship should never be based on quantity, on the largest number of friends. If we have few friends but friends with these characteristics, we know that they are real friends.
