If they answer, there's a conversation. This stage is that.
It isn't a negotiation and it isn't a pitch. You're both working out whether there's something here worth doing differently — which means the answer is theirs as much as yours, and it might be no. A conversation you've decided the outcome of in advance isn't a conversation, it's a delivery.
There's no approach that makes this land. There's only saying true things, hearing what comes back, and not arguing with it.
And if there's no answer at all — that's Stage 6, and it's a complete path, not the consolation one.
