So what does the non-shopper do on Black Friday? It’s a question I ask myself every year.

Today, there’s an ironic answer. I’ve already spent an early hour or two tabulating final expenses from the Asia trip, trying to remember where I had dinner on November 17 and hunting down receipts for various Perrier with limes.

While this is for reimbursement purposes, it strikes me that adding up expenses might not be a bad way to spend a day devoted to shopping.

Putting on the brakes before pushing the gas pedal.

Seeing how much has gone out — before sending even more in its wake.
