My therapist does this, and it makes me VERY angry! Her phone is always right next to her...and if a text goes off, she can't stand not looking at it. She has also answered the phone, or a text, or made a call during my session. She knows I hate it. It's hard for me to see her get a text, also, because she used to allow me to text her, and now she has a rule, no texting with clients. So I guess it makes me a little jealous when I see other people text her. She can't seem to sit down without having her phone next to her and I hate it!
