forgetful

This term describes a cognitive lapse or a behavioral failure. When applied to memory, it suggests a scatterbrained or absent-minded quality, often associated with aging or distraction, where the mind fails to retain specific data points.

When applied to obligations, the word takes on a more critical tone, implying a moral or professional failure. In this sense, it describes a conscious or subconscious neglect of duty, suggesting that the person has disregarded a promise or a responsibility.
