I hold on to only a few intense memories from my preschool days (back then, we called it nursery school). One is of making brownies. We stood around a long table, and passed a big bowl down the line, each child carrying out the next step in the recipe, whether it was to break an egg into the bowl, measure the flour, add the melted chocolate...by the time the bowl made it down to me, we were down to the boring part -- three stirs with a wooden spoon, then pass it on.
