I once asked for an extra appointment because I was having a challenge that week. The t had an opening and I went. The t did not making having the extra appointment feel like I had done something wrong (she did get paid for it -- so it is not like it was a favor) but she did become overly effusive about the fact I had come to her. That part was a bit much for me.

I have also gone to see other ts on weeks where I wanted a different perspective on something. So I throw it out there as an idea to consider or not.
