TOPIC: How to describe somebody who minds everything?

What about if we describe somebody who minds everything, even a little thing?

You asked about a word to "describe somebody who minds everything even a little thing."
First fo all, I'm a bit unclear about the meaning of your question, because "someone who minds everything" could mean either
-a person who takes care of everything (=a responsible person, positive sense), or
-a person who objects to or disagress with everything (=a critical person, negative sense),or
-a person who controls everthing (=a controller, usually a negative sense), or
-a person who pays attention to every detail(=a detail person, somtetimes negative, sometimes positive.)
I'm not sure which meaning you had in mind. Would you like to clarify that for us?
