Hi guys. The most common attack is the one you experienced Verbal Attack By Phone. Any arrival or departure area is the prime area for attack. You are most easily patterned by your arrival or departure from home!!
You might want to read my post on 5 rings analysis of stalkers and my own personal experience of being ambushed in front yard to see how this works in real life. In your case with very the little information I have unless they start writing you or leaving notes on your car (second most common point of attack) you are probably dealing with folks who think you are a lousy writer.
