mutual relations

what does mutual relation mean? does it mean that people who are in relation to other people always give benefit to one another? How do you define friends? Are they those people who will always be there for you and also those who genuinely love you for who you are? Can we not trust others who are actually close to us? Is there some sort of norm in how to create an altruistic relationship with others? How do you categorize people you helped in the past? How do you perceive your friends? Are they objects of psychological pleasure?Who do you go to when you have problems? Who is that one person who you can trust the most? These are the question which I think about every day. It has been a torture of not knowing which is right and wrong. I guess that when you have a relationship, any kind of relationship with someone, it just matters that you and him or her give benefit to each other. I suggest that before you decide on whether to make friends with someone that according to you does not fit into your own perception, please rethink about this. Because in the end we would have to look at this as something that are diverse in many ways.
