The answer you gave while overwhelmed can deserve another conversation.

Decisions made in a crowded moment are not lies, but they are answers shaped by the pressure of the minute rather than by what you actually want. Someone asked while you were mid-task, or tired, or holding three other things, and yes was the fastest way out of the room. Later the cost becomes visible and you assume you are stuck with it, because changing your mind feels like a character flaw. It is usually just accuracy arriving late.

If a commitment you made in a rush has been sitting badly, go back to it plainly. Say you answered quickly and would like to give a better one.
