Only when I don't know it is them. My NY apt had good security. Both NY and where I live now are private property. Without a name and phone number that i can confirm, I call the police. After all these years, my rage is so great I just can't say more than I was raised a Witness but I studied my Bible by myself and know for certainty that they lie. They are prob. good people but they better leave immediately.
An atypical witness engaged me at a local train station. I told her my family's experiences and my academic studies at Columbia University and life-long interest in the Bible. She seemed to be educated. I was able to keep my voice and comments calm. Four days later, a handwritten note appeared. Despite my credentials, she was certain I would want to learn from her. Why not learn from Charles Manson and write an article for publication?
She stood out b/c I also see them all the time at a major American transit station. They are completely withdrawn into themselves and their private conversation. They just sit there, gossiping. Anyone who wanted to purchase a WT or Awake would have to club them to get their attention. When I was a lowly child, I interacted more with people.
Of course, Michael Jackson wit his grabbing crotch never preached to me. The writhing on stage. What a Witness.
I endeavor to separate the individuals from the Society. Feelings of not being safe wash over me for days after they stop by.
