The Call is answered by all sorts, depending on the nature of The Call. When The Call is issued in the Service-to-Other, ourselves and our brethren in the Service-to-Other answer. The choice of whom a given caller is dealing with is not made by anything so arbitrary as take-a-number, or dividing up the cities. The choice is by type of activity, and if The Call one gives falls into a certain category, then that particular Service-to-Other alien group responds. Although there are many Service-to-Others groups at work, hundreds, in fact, this is far easier to maintain, as the group's scan can be set for certain types of thoughts, and all who trip the scan will receive a response. This is simple and direct.
When The Call is given in the Service-to-Self, unpleasant visitations can arise. This may confuse some people who feel that they were sincerely calling out of concern and love, in a prayer, for instance. Prayer is often encapsulated in a request to be saved from distress, so it is easy to see how self concern can creep into such a Call, even though this Call is structured in what some in human society would term as a loving or religious way and not at all self centered. Fear, in and of itself, is a mechanism that those in the Service-to-Self use to drive those leaning in that direction, those contemplating those thoughts, further in that direction. Those who are fearful are very much looking out for themselves. Yell Fire! in a crowded theater, and how many people think of others. They think of themselves.
