From my experience men often underestimate how often women face weirdos. While the whole conversation might happen only in authors head the initial comment of the guy is quite a regular thing. It is a form of bullying. The rest of the conversation might happen in the authors head only, but it’s sad that women have to face such behavior in the first place IMO. If you don’t think such conversation happens at all, you might get enlightened by the everyday sexism project, the related (audio)book, or just ask a friendly woman around you if they ever faced it. https://everydaysexism.com/
