That Bush quote has gotten a lot of attention, including this front-page NYT article. It's not about Bush, though, and then it's not even about how regular people have started saying "I'm the decider" to their spouses. Well, one guy did, but then the article devolves into an inquiry into who makes the decisions in relationships. I feel I've been had. An article I wanted to read -- one that whispered "bloggable" to me -- was just another dumb "relationships" piece.
Anyway, I rather like the idea of "I'm the decider, and I decide what's best" catching on in relationship talk. It's a cool way to exert control, but take the edge off it with humor, shifting the attention from your controlling behavior onto our presumably ridiculous President.
And have we figured out yet if "decider" is a word? In law, we use the term "decision-maker" all the time, so if "decider" is a word, we should be ashamed of our verbosity. However, if "decider" isn't a word, the President should be ashamed -- one more time -- of his language garble-making.
Dictionary check: "Decider" is a word! Recalibrate your ridiculousness assessment.
