Our reading
An editorial interpretation.
This is a riddle with a wry answer: making a plan is what amuses God. It expresses the view that human schemes are routinely upset by forces beyond control, so careful planning looks faintly comic from above. The tone is wry and fatalistic, poking at our confidence in the future.
