Perhaps real control freaks are perfectionists who probably felt in there life not good enough unless they become perfect, of course in the end no one is.
We all grow up with parents directing and in adult life perhaps the products of that are control freaks?
One can get ten or more people giving advise that contradicts each other but in the end an adult decides for themselves, by considering the group consensus and either takes part or none of the advise but manages to narrow his/her decision to one that resonates and better for them.
I often wonder Why does a person get so upset when they see a spelling error instead of understanding the message conveyed in the first place?
The message is what is important NOT the spelling , unless an exam situation.
Also the control freak is showing his/her flaw right off the bat when they had that need to correct.
