Take a good, hard look at this picture. The bands may be different, but this is going to be all of us when we reach retirement age! The children of the 60s who grew up with the Beatles and the Rolling Stones may be a little older now, but they still like what they like, and it's still part of their identity. Swap "Beatles" and "Stones" out for your favorite bands or artists, and you could be looking into your own future. That could be you, in a comfortable armchair, debating the merits of Katy Petty and Taylor Swift forty years from now.
This drawing serves as a reminder that very few arguments are new, and some of them last forever. We'd all be well served to remember that, rather than getting hung up on them when there are better things we could be doing with our time!
