Me too. When I first started, I was really frustrated until she could work me in to where I had a standing appointment. I wouldn't like have different appointment times or days every week.

My T has cancelled but only once I think. Other times, she's called me at work to tell me the person before me cancelled and if I'd like to come in earlier that would be fine. Also fine if I wanted to keep my regular time. Most of the time I've gone in because it didn't matter to me and I figured it meant T could get home earlier - at that time my appt was 8PM. Then one or two other times I really needed to see her and she added a 9PM appointment (stayed late for me) once and a couple of other times came in on Friday.
She isn't in on Friday's so she just came in for me once and for me and another person another time.

When I first started with her, I could only get there on Friday because I worked a half day and had no car, so had to take a bus to her. She came in just for me then, but I didn't know it until later.
She is very sweet to be so flexible and accomodating with appointments and urgencies. It is another thing about her that I appreciate and feel so fortunate that she is my T.
