Instead of having therapy at T's office, we went out to lunch!
We had a mix-up on the schedule, and I was at his office for my appointment an hour and a half before he thought I was scheduled, and his door was locked. I texted him to see what was going on and he was at an off-site meeting. He proposed we meet for lunch near the site of his meeting, since it would take him a while to drive all the way to his office. While I drove to the restaurant, he had time to finish his meeting, I got a table, and he met me there.
It was cool! It was not awkward, as I thought it might be. I asked him at the outset if I should pay him for this meeting (were we going to have a therapy session over lunch or what?), and he said no. No charge, due to the mix-up, and also he bought me lunch because he remembered it was my birthday. We had a good talk, and discussed my down in the dumps mood lately, as well as other topics.
