No, I would dislike that very much. I have set times for my sessions, twice a week at the same time both days, and I have never been close to missing a session. I know which bus I take on those mornings, to get me there on time, and it's so much part of my routine that I can't imagine forgetting it. (On those rare occasions when I have had to reschedule, I set up a reminder on my phone.)

If T had to phone all his clients he'd have to spend a lot of time on it, and I selfishly prefer him to do more constructive things with his time. Not to mention the fact that I wouldn't want him to be calling me all the time - it would feel like an encroachment on my integrity.
