If someone thinks that peace and love are just a cliche that must have been left behind in the 60s, that's a problem. Peace and love are eternal.
If you'll excuse a brief history lesson: most people didn't experience 'the sixties' until the seventies. Which meant, logically, that most people in the sixties were still experiencing the fifties-or, in my case, bits of both decades side by side. Which made things rather confusing.
