missingVSlost

missing is mostly absent; accentuates the lack of presence

lost is is more serious, implying gone without trace; accentuates the lack of ideas on where the thing/person is located

In many ways, they are interchangeable. But if you are talking about an object (say, the television remote), then to me, something that is missing is likely to be found again. Something that is lost is more likely to not be found.

Also, something that's lost has a sense that a person misplaced it. "The remote is missing again" does not say that any one person has misplaced i

Having found this topic, I don't need to open a new one.

What are their differences from "gone"?
My pen is gone;
My pen is missing;
My pen is lost.

Does "missing" and "lost" have the sense that it happens due to carelessness?
"Gone" may be indicative of natural wear-out.
This is my guessing.
What do you think?
Thanks
