I’ve been on the fence about the Oxford comma most of my life. I always felt that sentences looked cleaner without them. I always regretted that, sometimes, they’re necessary. Maybe that’s why I love Vampire Weekend’s take on the whole thing. Maybe the extra comma just seemed snooty.
The comma and I have become friends! And I’ll propose a style change for casual English: Just be okay with both.
We make rules to decide arguments and there should be no argument that, sometimes, commas matter.
Sometimes they don’t.
