Friendship is one of life's greatest treasures. Friends that are loyal are always there
to make you laugh when you are down, they are not afraid to help you avoid
mistakes and they look out for your best interest. This kind of friend can be hard to find, but they offer a friendship that will last a lifetime. Other friends may not be quite as loving. The pain caused by a friendship marred by betrayal is not easy to overcome. In fact, many poems find their inspiration from the joy brought about by a loving friendship or the pain caused by a failed friendship.
