I didn't think of that, but yeah I can see it. Of course Robin will be a lot more eloquent and even concede some of her point to Mineta. She's too vain to ever give up her beauty even with the drawbacks it comes with, and she's self aware enough to admit that. But again it's a way for her, and by extension the readers, to connect with Mineta on a deeper level that doesn't feel unearned.
