Really every C is neutural?

Yesterday I was riding in the front seat of the car with my mom who was driving us to the airport.
She was very upset about something related to the route we were taking.
Her face was contorted in a very unhappy, displeased expression.
I thought to myself, “That face cannot possibly be a neutral circumstance.”
The energy she was throwing off was super negative. I was doing all I could to stay in a positive or neutral frame of mind, but every word out of her mouth was some problem with the route – or really that she didn’t know every inch of the path like the back of our hand (there was no real issue in the drive at all).
Is every circumstance truly neutral? Is it possible that people do give off negative energy or is that not a thing?
Thank you so much!
