It may be hard to believe, but on January 1, 2015, we will be halfway through the decade known as the 2010s (the '10s? The teens? The twenty-teens? None of these sound right...). The passage of time being what it is, we guess this moment was inevitable. Still, we're finding it hard to get used to the fact that we're about to be in the second half of the second decade of the "new" millennium.
