This isn't quite fair. You don't know the person who you are responding to any more than they know you. Yes, their tone wasn't supportive either, but it may be going too far to say because a person isn't bothered by seeing a therapist's other clients that they "don't know much about feeling shame and feeling defective."

I, myself, always saw my therapists other clients coming or going, and it really was of no concern to me either. Like the person you were responding to here, I had so many other concerns, was so emotionally exhausted otherwise, that the least of my concerns was other clients. My lack of concern about other clients had nothing to do with whether I understood shame; I had more than enough of that to deal with -- so much, in fact, that I was seriously depressed, suicidal, and fairly regularly hospitalized. Other clients just weren't even on my radar; I was just trying to survive. I suspect that may be a bit of what the poster was trying to say.
