My T has cancelled twice on me at the last moment, once was two days before his wedding and he just misjudged his timing and couldn't make it to the office which although I was upset at the time it was understandable afterwards. The second time that the cancelled was last minute and I actually told him that I was upset/angry with him because although he had an excuse and apologized over and over, I was angry and he agreed that he was angry at himself for cancelling and misjudging time (again) and that I had every right to be angry with him.

On the other hand, he has scheduled me in for emergency appts. whenever I needed them, scheduled me for appts. while he was suppose to be on holidays/his honeymoon just to make sure that I made it through the week and a half off that he was taking and even came in for a day over Christmas break to see me. I think that those efforts of supporing me through my rough times makes up for two times that he has cancelled on me at the last minute.

The only time that I have cancelled on him was not necessarily a cancellation but when I was away for 2 weeks.
