Norman Haddow tells me that when he's teaching a dry stone training course, and talking about throughstones and batter and hearting, he sometimes likes to show his students a photo of Stonehenge and wait a few minutes and then ask them, "So why did it fall down?"
It's a good question because it points out the silliness of putting more emphasis on the fact that something did not last because it wasn't built in a certain way, rather than celebrating the fact that someone had the imagination and passion to build in the first place.
