#### 5.2.2 Relationship Building  
We defined _relationship building_ (\(n=180\)) as the human's desire for the ability to develop a relationship with the robot or a relationship emerges over time; these relationships can develop naturally or the human can dictate to what extent it would develop. Key identifiers of relationship building include the determination of how conversational a robot should be (\(n=58\)) if the human classifies the robot as a companion or casual friend (\(n=23\)) if the human could trust the robot (\(n=22\)), and if a human feels comfortable with the robot (\(n=18\)). As noted in Section 5.2.1, some participants preferred the communication be kept to simple commands or at minimum (\(n=18\)). Participants explained that they would like \"a little answer question, answer session...\" but not \"a full-blown conversation\" [PU-04,20]. In addition to those who wished for minimum conversation from the robot, some wished only that the robot understood them when they spoke, but that the robot itself did not speak back [PU-25,29,PJ37]. Some even wished to be able to change the amount of conversation (\(n=4\)). One participant explained, \"I would like the robot to be flexible in how it speaks, depending on the situation and the simplicity of the person it is talking to\" [PJ47]. Another added that the robot should self-adjust as when she is \"watching TV with my husband and talking about traveling or something, but if the robot breaks our conversation, I wouldn't like it, so I want the robot to be silent in that case\" [PJ15]. Our Older Adult (OA) participants spoke about mental health. Conversation between the human and the robot can serve a practical purpose, similar to OAs exercising to maintain their physical fitness. One participant explained that \"it is good to have someone to talk to\" and that \"even if it is a robot, having someone to talk to is very good for your mental health\" [PJ35]. Others included that regular conversations with the robot could \"be good for preventing her [[PERSON]'s] dementia\" [PJ-38,35]. Others indicated wanting more speech communication to prevent loneliness [PU02,PJ-05,39,41]. One participant's stance was that a caregiving robot could be a better listener than a person: \"As cognitive function declines, people repeatedly tell the same stories. It is firing to give a good response to the same story every time. I expect that a robot will always give a good response. I think it would be great if a robot could be developed that would enjoy listening to the same story even if it had to hear it hundreds of times\" [PJ12]. Participants who classified the robot as a _companion_ or _casual friend_ often related this to the relationship similar to pet and owner; \"I would love to have a robot that could also heal and watch over me like a service dog\" [PJ41]. Another explained that this would give the robot more of an emotional companion side similar to a service animal: \"If I'm laying around not feeling well, my one dog, that's my emotional support dog doesn't leave my side. Not even to take a shower, or go to the bathroom, I turn around, and there she is. So that's a good thing. And sometimes you're feeling down and maybe you're just down because you can't do what you used to do or whatever. So having that, that more of emotion, 'Hey, why are you down? You, you don't seem to be yourself. Let's, you wanna talk about it?' Something like that. Like a little buddy\" [PU20]. A few participants wanted their relationship with the robot to be closer than that of a casual friend, requesting it to be more like a close friend (\(n=2\)) or a family member (\(n=1\)). Several participants were weary of trusting a robot but stated that it is possible as you can build trust and confidence over time; for example, \"I don't know if you can trust a robot, but at least build confidence in that hey, this thing's just here to help you out\" [PU07].
