That is called selective hearing. We joke with my mom, she is hard of hearing. We were at the audiologist getting her hearing aides. They were testing what tones etc she had the most trouble hearing. The tone of my dad's voice was one of the tones she had the most trouble with. As he aged we noticed that when he talked to mom he talked in a quieter voice and then would complain when she couldn't hear him. (He had dementia) Now that he has passed away we can laugh about it. He was 89. Mom is now 91 and still going strong.
