Something that you just don't understand?

Ooo I know this one. Not everyone knows it, and believe it or not, McDonald's coke actually has a unique twist to it. Has a different recipe than your standard everyday coke from anywhere else.

I can't comprehend why people feel the need to blast music so loud it actually takes pictures off my walls. I literally had a neighbor shake the walls of my house with his truck's sound system to the intensity that it made a picture come off the wall. Every window of my house was rattling as if a jet engine was taking off next door. Trying to be civil I brought this up to the neighbor saying I had actual stuff falling off shelves because the vibration from his subwoofers were that strong. He just smiled and said that's what he was going for unironically. He's continued to do it periodically and specifically at night. Of course it's a no win situation cause there really isn't a good way to get him to quit it especially if other people in the neighborhood "likes him and his music." Which I've been told when I try to brooch the subject with other neighbors. Like, everyone is free to listen to whatever is their jam, but I shouldn't have to worry about my windows possibly shattering because of the constant bombardment of sound vibrations he keeps blasting. When he has to pop open his truck doors to keep the sound from breaking his own windows I think there is a serious mental health issue. Also at what point does this man just go fully deaf? Like at what point do they just wake up and can't hear anything anymore?
