On a scale from one to ten, how good of a driver are you? About 8, you say?
Have you ever noticed that when you ask someone to rate their proficiency, on a scale of 1-10, in something that they are supposed to know, in order to not seem overly confident and egotistical they usually say 8? That’s when I start from the assumption that they are most likely average when judged against a group of proficient people.
Me, I’m about a 2. But if you ask me how good I am at making a caesar salad, then I’ll say I’m a 9.
