A friend teaches primary school in Cumbria.
At the moment the kids are learning about evacuation during WW2. They have to write postcards, as if they were London kids writing home from the country. They find it hard to understand the idea of living in the city. At some point, they were told that a lot of the evacuees had no idea that, for example, bacon came from pigs.

Several of the kids have misunderstood this, and there are a few postcards where the poor evacuees arrived in Cumbria and were promptly presented with a whole pig for dinner. "I stuck my fork in it and it squealed and ran off" was my favourite.
