Like, I can remember that I spilled orange juice in the living room when I was 5, but can’t remember what I had for dinner last Tuesday.

Memories that aren’t accessed very frequently or for a very long time tend to be the first to go.

Other than that, it’s typically not a failure in “remembering” as it is a failure in writing or storing information. Eating dinner is such a mundane and boring event that we often just don’t even bother to write/store the exact details of it, while spilling orange juice is something that stands out as a unique event.
