I don't know. I think it would lead to weird conversations, especially during romantic events.
Jane: John, please put your pipi in my vivi soon as I believe I am properly irrigated.
John: Solid copy, Jane. I will proceed to initiate the insertion protocol.
Jane: I appreciate that, John.
John: You are welcome, Jane.
Jane: Oh my, John. That feels too big.
Jack: Sorry, Jane. That was me. I was distracted watching the news on the television when you spoke and must have misheard. I will pull out my pipi from your vivi, Jane.
Jane: Jack, you're so distracted! haha
John: Announcement! I have completed the insertion protocol, everyone. Jane, is it too big?
Jack: Ouch! That is me, John.
John: Jack, oops. I think I am also distracted by the news on the television. The story about the wiffle ball team going to a Major League baseball game was engaging due to the similarities and differences between the two sports. Nonetheless, I will initiate the withdrawal protocol from Jack.
Jack: Thank you, John.
Jane: Attention in the mess hall including John and Jack! I have decided to terminate my participation in the currently proceeding intercourse attempt. Please robe and vacate within 53 second per the terms of services. I love you, John, Jack, and Jake.
Jake: Thank you, Jane.
Jane: You are welcome, Jake.
Jack: Thank you, Jane.
Jane: You are welcome, Jack.
John: Oh my, everyone. The wiffle ball team was at the baseball game. Is not that interesting?
Jake: John, please pay attention.
Jane: Thank you for getting John's attention, Jack.
Jack: Jane, that was not me. Jake, please inform Jane that it was you that acquired John's attention.
Jake: Jack, I will. Jane, it was I that acquired John's attention.
Jane: Oh, Jake, thank you. Also, I retract my thanks to Jack.
John, Jack, & Jake: Noted, Jane.
John: Thank you, Jane.
Everyone: Okay, bye!
The End
See what I mean??
I ran a test script below switching everyone's names to the pet name Muffin to get a feel for it and have provided an analysis after.
Adapted Script
I think you're right. The thing that sticks out to me is that it becomes difficult to recognize to whom a person is speaking. For instance, let's consider the following line:
Jane tries to get the attention of everyone present with emphasis on two specific people. Since she used the pet name Muffin for both, it is hard to discern specifically who, so we need to conduct a logic analysis. Reviewing the history of the script until that line, we notice that only three characters have been introduced. We could temporarily assume that she is not trying to get her own attention (this assumption is discussed further below), so that leaves John and Jack left. Be that as it may, she does say everyone, which can imply that there are other people. She also explicitly calls two people by name, which could suggest that there are other people present since she would not have to have mentioned them by name otherwise. Still and all, she could be an inefficient speaker, so we cannot be certain either way. For the sake of deduction, we have to conduct a run through by holding these assumptions as true for the time being. Precipitously, it gets even crazier because there are three characters to whom she refers to by pet name at the end. Holding our assumption that she is not referring to herself, our previous deductions would be proven invalid. That would clear things up for us as we would now know that she is referring to the first two Muffins in particular, just not who those two would be by discernible name. It also leaves us a bit charmed as to who is the possible new Muffin. Per contra, that would be holding our assumption that Jane is not referring to herself. I have heard people call themselves by name, so we cannot be certain. I conjecturize that if we had enough data, would could analyze how often someone refers to themselves by name, then use statistical methods to analyze and conclude confidence percentages.
In any case, I agree with you. Using pet names does not measurably make this interaction less weird. But something still feels uncomfortable. I wonder what it is then. Any ideas?
