Three of them had forgotten. One meant to call and did not. Nobody found out until the chair was empty.
The 12:00 slot on the right was freed at nine in the morning, not at noon.
A reminder tells somebody about an appointment. A confirmation makes them decide — and somebody who has said yes turns up.
What, when, with whom — and the two buttons. Most people answer within the hour.
For anybody who has not answered yet. This is the one that frees slots.
With the address. Short, because at this point they are already leaving.
Sent the moment you change it, so nobody arrives to a locked door.
All of them off until you switch them on, and each on its own template so the words are yours. Outside the 24-hour window they go as templates; inside it, as ordinary messages — which is cheaper and reads better.
Bookings appear there with the name and number on them, move when you move them, and disappear when they are cancelled. Nobody keeps two diaries.
