I forgive leaving headphones in (or on) when interacting as long as I'm not hearing sounds from them. I use them to cut down on surrounding noise sometimes and it can help me focus on what people are actually saying to me. But good god, why do people play music and videos so that I can hear them??
You are more forgiving than I, perhaps I am old-fashioned in believing that when interacting with another human it's good manners to visibly give them your full attention. As for the rudeness of people infecting all those around them with their music/videos/podcasts, I want Old Testament God smiting
I can NOT get my mother to understand how HORRIBLE I find it when she sits across the room from me with her phone and plays videos on FB or plays games that make noise.
😬I'm so sorry you have to deal with that
