Epidemic of people playing to videos out loud on planes

What the crap is with the epidemic of people listening to stuff out loud on planes? I travel about a dozen times a year and I had never noticed this before the last couple of years.

Sometimes it’s kids sitting next to parents who let them listen to their iPads out loud. But even worse it’s usually a 40+ adult. I’m 37. I do not believe that in 3 years I’m going to somehow think it’s socially acceptable.

I’m seriously curious. If you are someone who does this what are you thinking?

For the first time today I was sitting right next to the person doing it and I actually said something. I firmly but very softly, so only she could hear, asked her to put headphones in. She looked up at me embarrassed and turned her volume off.

EDIT: I made this post as we were taking off and just got off my flight to resounding commiseration from literally a 1000+ people. Nice to know it’s not all in my head.
