Funny story...one of my closest friends didn't really introduce his kids to the music we listened to. At least not near to the level I did. Our kids are all around the same age. When they were in high school, their family is over at our house. The boys are in my sons room and my son starts playing Rush. My friends son is blown away by this "new band" my son has discovered.
My son, of course, starts playing along and acting like they're a new band. My friends son comes running out to tell his Dad all about the new band he just learned about.
He was a little disappointed to learn that they were his Dad and I's favorite band and that we used to go to their concerts together every year. lol
