The dynamics of magnets have never captured my attention, except during one middle school science test. I can't remember Bill Nye's explanation of magnetic poles or electron clouds, yet one lesson from the unit stuck with me -- opposites attract. The concept seems transferable to all aspects of life. Things that, at first glance, shouldn't go together often make the best pairs -- french fries and ice cream, dresses and sneakers, even light and darkness. But in these great pairings, is there a point where opposites become too opposite? In other words, can a fry become too salty for its ice cream, or ice cream too sweet for its fry?
