I wouldn't really call it teasing, more that I joke with them (I just about always initiate, but they respond) and pdoc does this.. what would you call it? Gentle therapeutic ridiculing? If I have faulty logic he'll say something like 'you might as well say' and then a funny example of something similar (like the classic example if you did something because of peer pressure, and your parents say 'So if everyone were to jump from the roof, would you too?'). However it's never mean-spirited and also never personal - my logic is faulty, not me, and it's not my fault for having faulty logic. (He's good with that last part but I think that's a pdoc requirement, as they see most psychotic people. If I have a weird or psychoticy thought he'll say something like 'But I don't quite understand. How does that work?' *I explain* 'Isn't that impossible because of ..?' Depending on whether the thought is merely weird or psychoticy, it might influence the thought. I like that because he listens, and accepts I have the thought and it bothers me, but doesn't say the thought is true or he also thinks it (which might reinforce it) while he doesn't ignore it and the content either.)
Therapist is a little more serious in that area and a little more jokey if we're just chatting (while sitting down and finishing up for example).
