It's often simple, but it's rarely easy. People are more important. Friends are the best people of all. Friends are those whose inconsistencies we can overlook. Enemies are people whose contradictions we will not tolerate.
Different friends are for different purposes.
Some people show love by feeding your face. Real love feeds your soul. Say people's names to them and smile. We are here to know, love and serve our fellow beings and to be happy with them on Earth. To have a friend, be a friend.
