An interesting question because from a very young age, as children, we are almost completely dependent on our family, specifically our parents, and we assume they love us and generally want the best for us in our lives. As we get older, we develop relationships with friends, and we learn to trust and share intimate information about our private lives and, without discernment, we trust and assume that the people closest to us really have the best intentions. This, in turn, makes us vulnerable to being hurt by the people closest to us. "The people that know us the most, have the ability to hurt us the most."
