How much notice of a therapist's cancellation do you like to have? It is not a big deal to me although I prefer not to be wasting my time getting to that person's office. I was more baffled when the woman would tell me weeks in advance - one it is not like I was going to remember and two the appointment was not such a big deal in my life that not having it was going to have much bearing on me. Usually I was happier not going.
