Perhaps the idea that everyone under a certain age was uprooted and sent off into the countryside during the Blitz would not be as much a part of young people's culture as it once was.
Think, for instance, of telling a young American child, "It's easy to get there. It's not like I expect you to be Christopher Columbus!" That would be clearly and immediately understood as a humorous hyperbole. On the other hand, make the same remark about Marco Polo and see the blank look you'll get. Admittedly Marco Polo travelled as far as Columbus did, only in the opposite direction and overland. But his travels were a best seller for centuries. Problem is, American kids don't have to learn about Marco Polo, they have to learn about Columbus.
For me as a child, "the atom" and "radioactivity" were modern stuff. Travel to the moon was the epitome of high tech. Now I'm facing a whole forum of people who mostly weren't even born yet when the last man walked on the moon in Apollo 17. You don't raise eyebrows to know it's a TRANSISTOR radio. You don't feel your heart race when they say "In Living Colour" or "In Stereo Where Available".
That's a shame. But then again I missed out on the thrill of western expansion or the race to the South Pole. So I guess we all get our kicks in our brief span on this earth.
When LWW was written, everyone knew about war relocation. Parents and older siblings were there. Yet I think it would do people good to LEARN about that, to experience the loneliness and fear children had leaving Mom and Dad in the city where bombs fell at night.
