Developing and maintaining meaningful relationships is an important part of all of our lives - it is natural to be curious about what it means to have, or for that matter, to be, a true friend.
Friendship can mean many different things and is always colored by the people involved. But as much as they can vary, there are some constants that are present in almost every meaningful friendship. Things like mutual respect, caring, loyalty and shared interests are all part of the formula. No matter what, your friendships should bring you happiness and support you in your endeavors - not make you sad or undermine you.
