Examples of positive, negative and neutral friction?

We always learned about friction as either being positive (tires gripping the road, brake friction for stopping etc.) or negative friction (causing wear or heat as in a bearing or engine due to parts moving against each other robbing power.)

I'm only assuming neutral friction is a balance of positive and negative friction that cancels each other but I can't seem to find any practical examples of this that would be appropriate for a 9th grader that does not involve deep discussions on plasma and ions.

I wondered if you could offer a simple explanation or example of what could be called neutral friction.

Thank You !
