But every Inuit parent knows you tell stories in the evening, when the child's mind is relaxed and expansive, and before sleep which carries words and images deep into the soul. Science is rediscovering that memories are consolidated at night, despite the previous generation's "data" which "proved" that children learn best in the morning. Children often listen better at night, they ask deeper questions at night, they imagine more vividly at night. In the brightness of day the mind turns outward to the world, a child often wants to be moving and active and socially interacting, and the things you are told in the morning may ping off all this buzzing activity like a moth pings off a moving fan. The things you are told at night are carried inward, they enter your dreams, they effortlessly become part of you.
