What is the most eye-opening thing a passenger has ever said to you?

"Can you change the station please? This song reminds me of my abusive father". 

I have thought on this sentence so many times since that ride and still have no idea how I should have responded.

One time I gave a ride to a chef who told me to never eat a restaurants weekend buffet brunch as it is just all the leftovers from the week... I can't seem to enjoy buffets anymore  😔 

Once someone asked me for advice on how to tell his foster son that they would not be adopting him but would be adopting his younger sister. I had no words of advice, I still think of this guy as a monster.

One time my passenger got a call while in the car that her father had passed away. It was the worst ride of my life. I felt so terrible just listening to her shock and sobs in the backseat. I spoke up and said I was so sorry but it felt so insignificant.

I have been thinking about this.  Some of the things I have heard are really not repeatable here, crude and unbecoming...   

There was one toxic woman... she was so toxic... until she said... "Oh, you are from NYC... well that explains a lot."   I had been very nice to her, so nice, and she was being horribly abusive... well anyway,  she pressed a button and I silently flipped...  My eyes must have given her an angry look... (one hell of a transition... I was really offended.)  I think she actually jumped... maybe even peed a little...  and on realizing she had crossed the line...  she became as sweet as your grandma.  The ride went from -100 to +10.  (I think she did not want her son to get a 1.)
