I hear you. One of the things (among many) I miss now that my wife has passed away is our BS conversations. We would talk politics, science, religion, sociology, and a myriad of other pseudo-intellectual topics. It was fun and stimulating.
She's been gone for almost two years now. And I've still not found someone I can BS with on a regular basis. My bro in law and I do the BS conversations, but he lives on the other side of the country from me. So we only get together a few weeks out of the year.
I miss my conversations about time travel, about quantum entanglement, about Trump, about homelessness, etc etc.
