What is the best way to respond when a stranger approaches me?
If you're by yourself, it's important to stay calm and think quickly; allot of these situations elevate or dissipate depending on the conduct of the people involved. Sometimes, someone will approach you and ask for the time or directions. You just have to decide; "does this person really fit into the setting or is he just trying to get close to me?" If you are unsure or if your suspicions are high then it's worth shouting or even walking away, doing something to break that tension is useful, as the stranger often hasn't committed to attacking you yet. If you can make the first move and put them off by telling them "stop!” then that will prevent the incident from going any further. You can always apologize later if you were wrong.
