Whoa whoa whoa. Did you not want her to have a goodbye ritual? So the two of you set one up. Either she is not being dishonest, adapted to what you asked for to fulfill your needs as a client, and forgot to shake hands...or you are complicit in her dishonesty because you asked her to change her normal goodbye ritual. Which is it? You can't ask a therapist - or anyone really - to do something for you and then accuse them of dishonesty because it is not in fact what they would normally do.

Also, when you say, "I also know some T:s are really genuine and have a routine for starting and ending sessions to make the client feel welcome and by that I also see my T is only doing this by technique, no heart!", by your standards they are no more genuine than your therapist. They have anticipated what a client might like better...but it's still a routine.

This is very blunt, but Sarah, we all want you to get the most out of this therapist, and when you start thinking things like this and resolve to be more "low-key" next week, you are not helping yourself.
