Re: When entering a room.
Boy, are you on target Dalyn!
In fact, how about extending the awareness to entering a parking lot. Recently, in the Seattle area, two purse thieves caught on mall cameras have been fast -walking directly up to women, punching them in the face and stealing their purses. On camera, it shows the victim just leaving a mall entrance door, and BAM, they are hit.
I wish more women would stay close to the door and survey the lot, and where they parked their car. The option of going back into the store to have someone escort you out is available at most malls. Also, while walking down a sidewalk, I have turned around and looked directly at who is walking behind me.
