The moving feast
The term ‘moving feast’ once meant Easter i.e. a date that shifts, but by fixed, agreed rules.
What people mean now when they use that term is the opposite. Nothing is agreed, everything drifts, and we've wrapped the chaos in a fancy phrase in the hope that no-one notices.
The honest translation is ‘we haven’t planned this project and don’t intend to do so. Let’s keep going until it feels like it’s over.’
A real feast has a menu, a table, a guest list, everyone knows when to arrive and when it will be over. This is the antithesis of most people’s projects.
