Our reading
An editorial interpretation.
A rueful, understated admission of second thoughts: the speaker now doubts an earlier choice, softening it with "maybe" and "not such a good" even as the exclamation mark hints at urgency. It is a moment of reassessment rather than a full confession of error.
