Female friendship is often selfish. A woman will choose love rather than friendship. What is the basis of friendship? Communication, support and understanding. Girls talk about life, about immportant and not so important things. Why does women's friendship end? Either their ways depart or appears something that they cannot share. For an eternal friendship both women need to be equal. Mutual respect is important! What about men? I think they are much simpler. They are always ready to stand up for a friend and stand up until the end. I think they do not require something supernatural and accept each other with all weaknesses. They get into various troubles which makes their friendship stronger. This is all I can say. Much depends on each individual.
