There is a specific kind of silence in a meeting where everyone knows the plan is wrong but nobody wants to be the one to say it.
I've been in that silence from both sides. The uncomfortable part isn't speaking up. It's realising you knew before you opened your mouth, and still waited for someone else to go first.
Leaders don't get paid to notice problems. They get paid to name them when nobody else will.
If the quietest moment in your week is the one where the most is at stake, that's not prudence. That's the cost of a decision you're avoiding.
