If you're bothered, do bring it up to him next time.

My therapist seems to match my presentation, and I'm just going to assume she means it when she's happy that I'm happy about something, since I am often not.

The one time she was not as happy was when I showed up and said I'd bought a house. She said she didn't know this was something I'd been thinking of, and I said I hadn't been thinking about it until a few days prior and bam, just went for it. So maybe she was not as happy as I was because she was thinking I was maybe hypomanic, but events panned out and over time she saw it for very good decision it was. Even so, I noticed that she had originally been sort of quiet about it. I was just too excited to care much.

As for testing: Yes, they expect it. Mine even suggested I test her, but she never explained what that would look like and why I should do it.
