I think that Margaret and Ellie have perhaps been reading my literary theory shelf when I'm not looking, because when faced with a great deal of snow, they immediately decided that they would build an igloo all their own.
They labored to make snow bricks. Of course, they soon realized that it was a lot faster to have me pick up snow on the shovel and drop it into the boxes for them to pack, but they were still working. Of course, Ellie wasn't clear that you needed to pile the bricks on top of each other for effective igloo construction, but they tried.
And then they realized that an igloo of their own was a much more plausible goal if they got other people, people with more design experience, and larger hands, involved in their building project.
Of course, we only really built a pile of snow before they got cold (there's a difficulty with gloves; either they are waterproof, but you lose all mobility in the hand, or they aren't, and your hands get cold super-fast. If someone were to invent a glove for small fingers that was waterproof, warm, and had mobility, I would be very pleased with them).
*Also money, but that's not really the point here, and if my children can become independently wealthy, that would be great. Less likely than the plan of theirs that I am about to discuss, but still, an admirable aspiration.
