When using this tri-part phrasal verb, i.e., "look back on," what is the length of time it refers to or can refer to? For example, it's common to say:
"When John looks back on his childhood, he can seen what a wonderful life he has had."
But using it for something recent "seems" intuitively odd:
"When John looks back on his meeting with Jane a minute ago, he realizes what he said was a bit rude."
So, is the general rule, use it with at least a week regarding past reference?
