Some folks think of people much as we think of cars on a highway: each with its own origin and destination, relating to one other only to negotiate lane changes and left-hand turns. For cars, closeness is danger, loneliness is freedom.
People are not cars. Cars are dead. People live. Living beings need one another, nurture one another, share destinies and reach them together. When you are alive, closeness is warmth, loneliness is suffocating.
People belong to families. Families make up communities. Communities make up the many colorful peoples of the world. And all those peoples make up a single, magnificent body with a single soul called humankind.
You are an extension of all people. Love them!
