From reading the other posts about listening to yourself or being aware I remembered a subjected I wanted to post.
What sets off your danger signal? What do you look out for?
A stranger asking for direction? a cigarette? the time?
A group of men huddled together?
A group of men walking toward you?
A person with a nervous eyes?
A person hiding one or both hands?
A person hiding their face with a cap?
A person hiding behind a corner?
All of that and more.... its kind of a learned thing - actually a "re-learned" thing... go back a couple of thousand years and we were very good at recognizing danger signs and dealing with them - 'cuz if we didn't we'd have been eaten. But thanks to the process of becoming "civilized" we've learned to drop that mantel of protection.... we've been taught to be polite, not to ask embarrassing questions, not to snub someone, not to cross the street when we see someone that makes us nervous....
Listen to that little voice in your head that yells out when something doesn't seem right - look around and pay attention to your surroundings - most times when something goes bad there are signs that you aren't pahying attention to.
Gavin de Becker, who has written a number of books and runs a threat assessment consulting company, wrote a book " The Gift of Fear" that deals with this very topic - its aimed at women and children but everyone can benefit from reading it.
A better description of his book from a reviewer on Amazon.com "Perhaps we have a bad feeling about someone we've just met, or a little gnawing perception that a situation just doesn't "feel right," or perhaps even a fear that a co-worker might do something harmful. What de Becker, renowned expert on violent behavior, explains here is that instead of shrugging off these fears, we need to listen to them, see why we're having them, and act accordingly. Far from being silly intuitions, often these can truly show when something is wrong and violence might be imminent; if listened to, along with information about how violent people behave, these feelings might protect us from harm."
