Hearing about the busyness of someone else is never interesting, as the busy person often presumes or hopes the listener will express either concern or admiration, neither of which is a likely product.
A busy person may be one who has trouble prioritizing or simply procrastinates. Or perhaps they lack proper staff to handle their affairs. I, for example, suspect the president is a “busy” person, but would never gripe about such given the administrative apparatus at his disposal. Oppositely, how could someone like me (for example) ever claim “busyness” with such a narrower purview of responsibility?
And yet here I am, resisting the urge to do just that. Of course, if I were truly busy, I wouldn’t be writing things like this. I’m always free for this.
