I need a relatable image pls

I hate being neurodivergent and having socially unacceptable hyper fixations what am i supposed to talk about when im sitting in silence with my family in the car? The Roman’s views on different sex acts and how they carry into the modern western mindset? Latin poets writing about how ugly each other’s penises are?
Anyway I need a reaction image or whatever that properly expresses how it feels to stay quiet in this scenario. Please. Thank you.
