I also thought it was a rule that a therapist can't say hi to a client first. But CT said they just can't say HOW they know you. But I had an aha moment about an hour ago (I work nights). I'm giving OT a lot of power over me. No more. She's getting a nice firm hello next time. Heck, maybe even a How are you. And trust me, there's protecting a client and then there's what she's doing. And if it's me giving off the mixed signals, then I'm about to fix that. And by using her first name in the hello I'm explicitely giving her permission to use mine.
