I was always more likely to praise him than to thank him, if those are two different things. He always looked maybe just a little embarrassed but definitely pleased. I don't think people can get enough praise or thanks (not counting from obsessive people or the overly insecure). And then I always said thank you at the end of the session, but that was more generic. I was sorry I couldn't write him at the end of our sessions, but I just couldn't.
