When I went to Mexico with my family back in the 80s, we were on the beach and some Mexican children wanted to build sand castles with us. We started working away on ours while the Mexicans started working on theirs, and after awhile we looked at each others' work and were all, "What the hell are you doing?" We were building our walls and toothed ramparts and square buildings while the Mexican kids were building Mayan pyramids. Cool!
Fast forward to a few years ago when I started watching a lot of BBC Kids with LE (and by the way, WTF is up with BBC Kids, running the same three episodes of three shows for three hours-- when LE was born, there was like 5 hours of a variety of programs, and it's dwindled consistently ever since). I noticed that when little BBC kids build sand castles, they're much like the ones we built, but they're very insistent on having a flag. It's like you're not building sand castles unless there's a flag.
Fast forward to today. In one of our playgrounds, new sand has appeared. It's been dumped in a pile in one corner, ostensibly to be raked across the park later, though given the number of kids crawling all over it and throwing it and doing funny kid stuff, the sand will be moved naturally within the next few days. It's perfect, beautiful soft sand, with exactly enough moisture for sand castle building.
How great is that? They're all building little Cappadocia and Hittite structures. The whole sand hill looked really cool, like a Miniatürk Cappadocia postcard, but LE kept running away to the slide and I felt creepy taking pictures of everyone else's kids when mine wasn't there.
They're even making little caves!
