Isn't this exactly what I said several times? I said more than once that stalking is a regular appearance near someone's place of living and staying there for no other purpose than staring. As far as I know, "regular" refers to a PATTERN. Don't pretend that my argument was something it never was. It's a "straw man" logical fallacy and generally used (as any logical fallacy) to manipulate the conversation.

Where I live, if you do what I described above and get caught you can easily be served a restraining order and I know of cases when it happened.

I am not using legal definitions here. I am not a lawyer and I don't give a crap about how stalking is defined legally either in my state or any other jurisdiction. In my layman terms the above description qualifies as stalking and warrants calling the cops on the one who does that. If someone starts appearing near my home regularly and it looks to me like they stay on the street with the intention to stare at the house and they do it regularly (should I say
"regularly" ten more times?) I am going to call the police because I define this as stalking and this creeps me out. How everyone else thinks of it is of no concern to me.

If a therapist believes that a client has been stalking them for some time and decides to terminate the work for that reason, they have the legal and ethical right to do so as long as they document all instances of stalking in their records. No one expects a therapist to put up with any crap from a client and no therapist will get in trouble for terminating therapy if they were stalked. Everyone can have their own opinion about that. You can agree with that reality or disagree with it but it is a reality and your opinion will not change it.
