I get 45 minutes sharp every time (he doesn't have breaks between clients). He usually says something like "let's stop here for today" and then walks me to the door, sometimes saying something conclusive about our session others nothing, we say bye and that's it.. Because he doesn't allow for breaks in between, a few minutes prior to the end, the bell rings (his next client) and he leaves the room to open and directs the other client to a separate waiting room (so that we don't fall to each other). So I know we are about to end. Yes it is hard. It's like an all of a sudden reality check.
