Is it natural to say someone is "ordered" in order to mean s/he is a well-organized person. From what I saw in the dictionaries, "orderly" has more of a meaning like "peaceful/well-behaved" when used to modify a person. And again according to dictionaries, we can call a place or someone's life "o...
