Take lightly what you hear about individuals. We need not distort trust for our paltry little political agendas. We tend to trust soulless, carried information more than we trust soulful human beings; but really most people aren't so bad once you sit down and have an honest, one-on-one conversation with them, once, with an open heart, you listen to their explanations as to why they act the way they act, or say what they say, or do what they do.
Quiet people always know more than they seem. Although very normal, their inner world is by default fronted mysterious and therefore assumed weird. Never underestimate the social awareness and sense of reality in a quiet person; they are some of the most observant, absorbent persons of all.
