Concussion

So one of my favorite cheap shots is to say that someone has all the critical acuity of dental floss. But then, this morning, on my walk to work, I got to thinking.

(Most years, the quality of my thinking by this point in the term has oozed away in unexpected directions, knocked off center by fatigue. It's not necessarily bad, wrong, or irrational, but it's certainly unpredictable.)

So anyway, I said to myself, That's actually a pretty bad metaphor, because dental floss gets into those tight, dark, crevices and works out the debris that rots and corrodes. It's actually sort of a compliment to say that someone's critical thinking skills are like dental floss.

I need a vacation.
