On filling up.

An economist in the New York Times made an incisive observation about why rising gasoline prices bother us so much, which I found funny because it echoed a sentiment I expressed in this Bweinh poll last week.

For the several minutes that I stand at the pump, all I do is stare at the growing total on the meter — there is nothing else to do. And I have time to remember how much it cost a year ago, two years ago and even six years ago.

Yet I have no such memory about the prices of items in any other category. I have no idea how much milk was six years ago, how much bread was three years ago or how much yogurt was a week ago. But I suspect that if I stood next to the yogurt case in the supermarket for five minutes every week with nothing to do but stare at the price, I would also know how much it has gone up — and I might become outraged when yogurt passed the $2 mark.
