The amusing thing about that for me is that, as someone with perfect pitch, I've used the pitches made by failing components in my car for diagnostic purposes without even thinking about the fact that most people can't do that without technological help. It's just... you know what pitch it is and therefore how fast it's moving/rotating/oscillating. Everyone knows that about everything they hear. Right?

Makes me wonder how many lived experiences I take for granted that are totally different for others, and likewise the lenses through which others see the world that I would never imagine.
