My kids and I like so much of the same things, too. I think that is a healthy relationship. I got so much bullshit from my sister when I said I could see me and my older daughter going to a bar (when she is of age, of course

) and she just thougth that was so wrong. You couldn't go to a bar with your CHILD...I laugh with my kids, I cry with my kids. I am 19 years older than my oldest daughter...not that much has changed in 19 years. I still remember what is was like to be a teenager-the joys, the heartaches...I think parents that can do this will have a stronger relationship with their kids and when they need them, they will turn to the parents (hopefully) instead of someone else or trying to handle it on their own.
As far as music, I can remember my oldest "discovering" Pink Floyd!! She was just amazed! And my youngest asked me if I knew who Bob Segar was!

It's so fun to watch them experience 'older' music knowing that they enjoy it as much today as we did then. That has to say a lot for the music, too....it spans the generations and has that same effect...
