SCENE_01
The ping lands mid-sentence
You are three paragraphs into a design doc, the argument finally lining up, when a Slack notification slides across the corner of your screen. It is a teammate asking which endpoint handles refunds. You answer it in ninety seconds. Then you sit there, cursor blinking where you left off, and the thought arrives fully formed: "Every interruption proves I can't protect my own time."
SCENE_02
You start counting instead of writing
The doc stops being the thing you're building and becomes evidence you're gathering against yourself. You scroll back through the morning's tabs, tallying how many times you got pulled away, as if the number itself were the verdict. You start closing Slack between every paragraph, then reopening it out of a different fear, and the doc gets shorter passes each time you return to it, because half your attention is still on the tally.
SCENE_03
The tally was never the whole page
A more accurate read: the ping cost you the endpoint question and a bit of re-entry, not the doc. Open your calendar or a blank note and mark, in one line, how much of the doc actually got written today versus how much time the interruption itself took. The gap between those two numbers is usually smaller than the story you told yourself while counting.
