Ah, the classic developer-manager communication gap! The first scroll says "Yes" because technically the task is done. But unfold that scroll and suddenly there's a novel-length explanation about how yesterday's "finished" feature spawned a fresh hell of bugs that now need fixing.
This is why standup meetings that should take 15 minutes somehow stretch to an hour. The manager just wanted a simple yes/no, but developers live in a world where nothing is ever truly "done" - there's always another bug lurking in the shadows, waiting to ruin your weekend plans.
