There's the kind of forgetting where you once had information in your head that you can no longer retrieve. The phrase "it's on the tip of my tongue" captures this kind of forgetting nicely.
What I'm looking for is a word or phrase for the situation where the information is still accessible, but wasn't triggered in the moment you needed it.
Examples
- "At 1:00, I'll turn off the oven." You get caught up in another task and check the clock too late.
- You go to the basement to get a tool only to return minutes later empty handed
- "Oh! Today is May 5. I should stop reading Stack Exchange and wish Soandso a happy birthday!" You reach for your phone and realize you left it in the basement. You find yourself browsing Stack Exchange on Monday again and realize you never sent that text.
Ideally, this would be a single word or phrase you'd use in everyday conversation. Ex: "Sorry, I ____." Or "Sorry, that was ____."
Note that "Sorry, I forgot" can also mean that you don't remember ever being told about that. So "forgot" is too vague for what I'm looking for.
