This episode pairs a vivid comparison for a tedious experience with an idiom about staying active and acting promptly. The contrast makes the two expressions easy to remember: one describes time dragging, while the other praises someone who keeps moving.

Cultural note: “Like watching grass grow” is playful hyperbole, not a literal claim that grass never changes. “Don’t let the grass grow under your feet” is a figurative push to get moving; depending on delivery, it can sound motivating or impatient.

Keep exploringOne grass image means “this is painfully dull”; another means “get moving.” Explore how the wording flips the feeling.
