Does the line in bold seem natural?

Hi teachers, does the line in bold seem natural in the context?

A - You seem to be really good at having these personal conversations. No wonder since you do it for a living. Being a shrink must be a fascinating job. Do you like it?

B - I do. But I didn't know that was what we were doing now.

A - Then why are you asking me all these questions?

B - I just thought you wanted to talk about what happened, that's all. But I'm really not here as a psychiatrist, I'm here as your friend.
