I finally understand why my cat stares at me without blinking for three minutes straight before asking if I've seen her toy from 2019. She's been studying my technique. Last Tuesday I spent forty minutes analyzing a spreadsheet, and my roommate interrupted exactly seven times—each one a different question, each one solvable by literally any search engine. On the eighth interruption, I just started answering his questions with increasingly complex spreadsheet formulas. He's stopped asking. I've also stopped understanding my own work, but at least there's silence now.
