I adore my psychiatrist. His phone calls are hit or miss. There are times when he's all business, "just the facts, please" and sometimes he's his usual warm and supportive self. I think it depends on how many emergencies he has had to attend to and how many calls he needs to return. It's like holding back the ocean, but try not to take his tone personally. Go by how your relationship is with him over-all. If you want to bring his phone call tone up with him, write a letter about it and share with him at next session. It might make him more mindful for the future when he speaks on the phone with you.
