I know what's best for you and you just need to trust my approach.

I don't need therapy. / I'm done with supervision.

Confidentiality is overrated. / I will discuss your case with mutual colleagues / trainers.

Let's meet for a cup of coffee sometime.

Any oversharing about self / other clients in an inappropriate way.

You will get better in .............. (time) / Therapy will (definitely) help you with ........................

In your situation you should ... / You have to ............... (any obligation other than therapy admin stuff or any unsolicited advice)

I understand you completely!

Your religion / belief / feeling / experience (etc) is wrong. / You are wrong (and I am right).

I'll introduce you to a friend of mine / to a relative / to another client.

Why don't you kill yourself already? (I actually heard that from a therapist who gave a lecture at my uni when I was an undergrad student ... really scary that such a person is practicing!)

You are mentally ill / abnormal / weird / ...

I will cure you of homosexuality (again, I read an article by a therapist who claimed to do that, just a few years ago ... scary to know she's allowed to practice)

I could think of many more.
