Sociology: Trust

How can you tell whether someone is a rapist or a murderer? You really can't unless you develop an intuitive sense which comes from careful observation of people. Even knowing their full past won't help if you're their first victim. Many crimes are done by people you've always thought would never do such evil. So how can you trust anyone?

There is no answer for 100% accuracy but developing your perception can help tremendously. Let's consider the case of a girl trusting a guy. How can you tell whether your friend or boyfriend is what he appears to be? If he seems too nice, something may be wrong. If he doesn't tell you much about his background, be alert. If no one trustworthy you know backs up his character, watch out. If the people hanging around him seem to be decrepit, nasty, or ___ (insert negative word), stay away. Though a lotus can come out of mud, there's a good chance he's just a mud pile pretending to be a lotus.

There's many books out there on this topic. It's best to read a few and examine from other peoples' mistakes. Learning from experience is a hard road here.
