For me, I find most things can be fascinating. There are so many domains I have zero personal, surface-level interest in, but have nuances that are super interesting.

When someone else has that spark, and their eyes sparkle, and they beam as they talk about "their interest"? Idk, I love that. It makes me feel good to hear them. I feel like we both come away better for the conversation.

I guess not everyone is like this?
