A Shared Plan Needs Clear Edges

A thought experiment: two friends agree to meet regularly. One chooses the café each time, within a budget and schedule they’ve already agreed on. But changing how often they meet affects both people, so that part calls for a shared decision.

The distinction matters: agreeing on a shared plan doesn’t hand over every choice around it. Some details can belong to one person; changes to the commitment itself may need both people’s consent.

Making that boundary clear can protect autonomy and reliability at once. It also gives each person a fair way to say, “That detail is yours to choose,” or, “This change needs a conversation.”
