How to Say Hi to Your Therapist on a First Day

How do you say hi to someone on a first day? It's like, how do you say, I'm a third person? Because also for remote sessions, you're just like, okay, bye. And you're good. There's no physical movements you need to do. They don't need to see me get out of my seat. But yeah, for some reason right now, my thoughts are just like, wouldn't it be like a violation if I'm asking her about her personal life? Like, who am I for her to share her personal life with? You know, I usually feel that way.
