The booking thread, and which of you keeps it
The booking thread is the single written conversation where the date, the hour, the length, the figure and the address are all agreed and kept in one place.
Everything is arranged in writing, in one thread, with [email protected] as the written address while this domain has no other route. The thread is where the date is fixed, where the length and the arrangement are chosen, where the figure and the advance half are named, and where the address arrives.
One thread, not two
When two people are travelling together the natural instinct is for both to write. It is slower. Pick the partner with the freer day, usually the one who is not in sessions until six, and let that partner hold the thread from start to finish. The other can read it over a shoulder.
What the first message should carry
A date, an hour in Amsterdam time, a length, whether you want one therapist between the two of you or a therapist each, the name of the woman whose profile you read, and the part of the city the room is in. The booking page sets the order out.
Naming her yourself
The choice is made by the two of you from the profiles on the roster. Name her in the thread and the reply says whether that hour is free. If it is not, the reply says so, and the two of you decide what to do next.
Why it is kept
Because an evening arranged around a working agenda changes at least once, and a thread is where the change is read against what was agreed. The address is written near the end rather than the beginning, once the hour is settled.
