I don't think it's arrogant to introspect your own thoughts about how a common social situation makes you feel, especially in a conversation about social dynamics.

You're the one coming off as arrogant and judgemental here, by my reading.

Plus, I would argue that being resilient to people with shorter attention spans or worse memory (due to how their brain works, mood, or emotional state) is an important factor in discussing what communication style is most generally effective!
