Like you'll notice some minute detail and the next thing you know you're drawing all sorts of conclusions from it?
"Whoever owned this car before me was probably white. There was a car insurance card stuck in pocket of the owner's manual. That's awfully inconvenient--nobody wants to fuss around digging in the owner's manual at the side of the road, so they must not have anticipated needing the insurance card. That means they didn't expect to get pulled over by the police...so it was likely somebody who didn't have to worry about racial profiling."
I'd say this is a waste of my time but that would imply I'm consciously spending time on this instead of just doing it without thinking. :V
