Concentrations of short lines are persons. The yellow and grey squares, long lines are forces and currents in the persons' lives. The work as a magnetic field, aligning the persons that are under the influence of the force. Some people are aligning to the wrong force, not the force that influence them in reality. Some persons are so weak, they dissolve in the strong current. And some persons just pretend to be influenced, so they look like everyone else(the figure in the yellow square).
