Spare us the exhausted sigh; the fly in the jar works just as hard and gets precisely as far.
The line is aimed at the person who has mistaken motion for purpose and fatigue for proof of virtue. You arrive with the sigh already prepared, the weary little performance that invites everyone to admire how much you have been carrying, and you deliver it as though exhaustion were an achievement rather than a symptom of poor decisions. Notice that nobody asks for the details. They have heard the same account before, the same vague duties, the same heroic busyness, and they have learned that asking only encourages another chapter. The fly in the jar is the unkind part because it names what you refuse to see. It buzzes with tremendous conviction, bounces off the same glass, and ends the day exactly where it started, convinced of its own industry. You call that a schedule. You call it commitment. You call it being stretched, as though the word stretched were a compliment rather than a description of something about to snap. The line lands best when you announce how tired you are in a tone that expects sympathy or praise, or when you mistake being unavailable for being important. The truth is colder. Effort without direction is just noise with a pulse, and you have been very noisy indeed.
