Try this
- State what you remember agreeing and ask whether the other person understood the same thing.
- If the versions differ, clarify the next plan in concrete terms. Do not rely on a vague phrase that caused confusion the first time.
A worked example
“I thought we agreed to call Sunday. Did you understand it that way?”
An invented example to adapt, not a real exchange or a script you have to follow.
Before you leave it here
If the agreement was unclear, make the next one explicit rather than arguing over an assumed promise.
