"Too high. That's what went wrong. We put them at the top of the posts and all the light went into the hedge and the path stayed dark."
Tidy went very still. "We've been hanging them at the top of the posts all day."
Every lantern on the path came down two feet, which took an hour nobody had, and which was the single most useful hour of the entire day.
