Youngsters these days.

My 24 year old grandson finished his tour in the service recently and has been staying with us for the past several months. He got himself a good job, to help out and take care of himself, while deciding what to do in the future - back to school, etc.
After he got a few good pay checks, I joking suggested he buy his Pa a new CD player. If looks could kill. "Why would you want a new CD player?" He asked. I told him "just to upgrade the one I have". "No one buys CD players anymore" he exclaimed. "Then what's your Idea of fine Audio, a WalkMan?" I asked. "WOW! There's not even any such thing as a WalkMan any more" he said. To which I replied, "Ya there is, we have a guy on our forum who swears by em". He just rolled his eyes and said "No - Streaming! Using an iPhone or iPad you can get a streaming package and get all the music you want". "Why would I want to do That?" I asked "I have hundreds of great LPs and CDs, that I'm perfectly happy with." To that he replied "OK Boomer".  I guess that meant he knew I was right.
Why is it that youngsters just don't understand the love that some of us old folks have for our old LPs and CDs and we  have no interest in paying for another monthly service, to listen to all the music we already have?
