That sort of assumes there is ONE common sense to teach, buds.
Ain't you ever heard Einstein's quote that "Common sense is the least common of the senses"? I don't quote him because the dude was a genius... I quote him because he was right.
Seriously: WHOSE common sense are you wanting to teach? Yours? I'm sure you'll realize that's your version of sense. If you're a Republican ... or a Democrat... or a Fundamentalist.... or a Radical ... your common sense will be different from the rest of those, yeah?
So best you can hope for is that your common sense definition isn't totally banged against a wall. Teach it to someone? Forget it! :)
