Stupid questions are provocations.
Questions about assumptions are provocations. (Sometimes these sound like stupid questions.)
Provocations yank us off of autopilot. They prompt us to consider change. Dwelling on a question can be really valuable.
Provocations shouldn’t prompt kneejerk negative reactions. Humble, introspective response to provocation should be our default. This is a thing to practice, a goal to work toward, a direction to move in.
The people who provoke you probably drive you nuts. But maybe they also prompt you to grow.
