I think you might be reading in to this a little too much. I would encourage you to be honest with your feelings though. He needs to know how divulging even the smallest bit of personal information has an impact on you. I'm sure he was just making an example, like you said. But I'd say something about how it made you feel.
Ts aren't supposed to be our friends, its okay to not give a flip about what's going on in their lives. Our sessions are about us. Their personal lives be damned.
Hope that helps.
