"Just decide" meets "let me check."
D wants the call made. C wants the call made correctly. Both are right, and both read the other as the problem.
Endless caveats. Questions that feel like obstruction. A pace that costs momentum and burns the window for action.
Decisions made on instinct. Risks underweighted. A willingness to commit before the work has been properly thought through.
Separate the decision from the diligence.
For D: give C the question in advance, even by an hour. Most C resistance is about being asked to commit in real time. For C: name your top two concerns up front rather than listing all of them. D will engage with the priority; the rest can follow.
