For starters, it seems like your questions might also play along the line of questioning, that we can picture the person on the other end looking to just jack off to the mental image of the visit he is trying to plan, and question if it is a timewaister just looking to get off on this comunication, or does this person actually have intentions to book an appointment.
That's the first thought.
Second is, visits entirely planned out before we even meet in person, is trying to fulfill a pre-established expectation to live up to, rather than to just expierience the moment. We don't want to fill a role.
There is a matter of fact ways to discuss these things, but many providers find all these questions too time-consuming, for what might likely lead to no visit. It's 1 thing if the providers seen you before, and knows you are serious in your questions for followup appointments. But for a first timer... There are a lot of people who will reach out ask many questions and never follow threw, you might be redflagging yourself before the initial visit ever happens.
We don't want to lay every one of our cards on the table. People who ask us so much about our boundaries, is often looking to push them. It raises distrust right away when what someone wants to know is the no's, rather than asking for what the yes's are.
