Young or Uncultured?

Okay, I have lived with Brad and Michelle for almost two years now and during this time, I have been subjected to many different kinds of movies and music. Yet as I continue to learn about the popular culture before my time, I am still at a loss as to what is going on half of the time. Though I now know who the Beatles are and U2, etc, there is still a lot I am uneducated about. There are still times when Brad and Michelle will be talking about somebody (let's say the name is Kate Bush) and I will prompty turn my head and comment "Who?" My response is usually either a shudder, a cringe or something getting hucked at me, before hearing "Go to your room!" In my defense, I must confess my era of music was different than theirs. Anybody born in the eighties can sympathethize with me that our bands included the Backstreet Boys, Hanson, Britney Spears, Christina Aguilera, and of course, the much loved Spice Girls. This was my repertoire of music, the pop era, and I enjoyed it very much. It's gone now, especially in my house where it wasn't even considered "real music", where the Spice Girls are compared to something along the lines of a cat in a microwave oven. (Okay so I add libbed a bit, but I'm not that far off).
Yes, most of this has to do with the age difference (although on the lifespan development chart, Brad, Michelle and I are in the same stage in life - early adulthood). Most of the music and movies they enjoy are either from before I was born, or shortly thereafter, when I was just a toddler, probably not even knowing what pop culture was. This gap is always evident when the three of us play games such as Scene It or Trivial Pursuit Pop Culture where I practically don't exist in the game, as I barely move or have long enough turns. But it is my way of learning as well.
This occurs with movies too. I have a long list of movies that I am "expected" to watch because "oh Chrissy you have to watch that movie." Of course, once again, far from my movie repertoire of Stepmom, Harry Potter and Left Behind movies. However, I am willing to expand my repertoire, as I am interested, yet I don't think I will ever be up to par with my "family." Maybe they're the weird ones, knowing way too much about popular culture. I think I may do a study on this very phenomenon. Perhaps I am among the norm (erm, somewhat). Who knows? I guess I will continue to be sentenced to a life of pillows being hucked at me because of my lack of knowledge about Queen.
