I would not worry too much about T things outside of one's hour; we can't know what T's do in their own time, with their schedules, etc. A call to the person's house "down the street" after he left you could have revealed the person didn't need them to come anymore or he could have needed to go to the office for something and then go to the person's house, "down the street" could have meant any number of things. It does not sound like he's that far away if it only takes him 20 minutes to get to/from his office; takes me almost that long to get out of my development.

I worked with my T for almost 10 years then I had to move and it was 10 years more before I saw her again, new location, new state, etc. and saw her another 10 years; I think of all that time as one, that I literally saw her 18-20 years but "knew" her for almost 30 since the time in between was as important to my therapy experience as the time actually spent in therapy.
