Friendship requires leisure. This fine cultural form cannot survive without the time and leisure that are its lifeblood. I love the East Indian custom of standing next to someone in silence, probably just a step in back of him or her, if you wish to make friends. Silence, waiting, time, respect for another's space–these are the elements of friendship.
Diversity is the magic. It is the first manifestation, the first beginning of the differentiation of a thing and of simple identity. The greater the diversity, the greater the perfection.
