I do believe most curators - maybe I'm only speaking for myself here - want to be artists on some level. Curators must have an innate interest in what an artist makes. And they certainly have their opinions and criticisms, and the always ask, "How would I have made this, or how would another artist make this?
In the spirit of being a reflective practitioner of ourselves we must notice your own behavior as an educator and realize how it influences other. Recognize your privileges: race, gender, ability, career, citizenship, language is all privilege. Imagine how you feel in the visitors shoes and adjust to best help them process and contextualize.
