I also put other. Not because I couldn't talk to my T about certain topics (actually quite the opposite, he makes sure to mention that I can tell him whatever I want), but I think it depends on wording. As in it's okay to tell your T you are mad at them or that you are jealous of their wife or children. But it's not okay to yell at your therapist because you are mad, or to insult the ones they love and so on. As long as it is worded in a respectful manner, everything is okay to be talked about.
