Having a job like social worker or working for kids, can make the people in authority mean/angry even when most of the time they are nice and normal human beings with their own intricate shades of gray. It's just the system has a tendency to erode the natural sweetness that people have.

I just read something that I found so helpful. Psychologists have discovered it's not 'self-confidence' that makes people happy, it's self-compassion. Confidence has an aura of smugness and a hidden, cover-up victim mentality where you think other people will always hurt and fight u. It's a dog-eat-dog world out there for the 'self-confident' person and what if they are the lesser dog?
