Introduction
In professional communication, admitting a mistake—especially something as common as forgetting—requires careful wording. A poorly chosen phrase can make you sound careless, unprofessional, or inattentive, while the right phrasing can preserve trust, show accountability, and maintain credibility.
Instead of directly saying “I forgot”, which may feel blunt or informal, polished alternatives help you acknowledge the oversight respectfully and responsibly.
