slip someone's mind

Escape one's memory

When something slips your mind, you forget it—not through carelessness but because it simply failed to surface when needed: I meant to call her back, but it completely slipped my mind.

The phrase implies the forgotten thing was known but temporarily inaccessible, often used as a mild excuse for oversight.
