Friendship is the most wonderful relationship that anyone can have. Ideally a friend is a person who offers love and respect and will never leave or betray us. Friends can tell harsh truths when they must be told. There are four different types of friends: True friends, Convenient friends, Special interest friends, and historical friends. To have friendship is to have comfort. In times of crisis and depression, a friend is there to calm us and to help lift up our spirits.
