As usual, the Onion is spot-on. There's a special kind of despair that washes over me when I'm starving at my desk and staring at a bruised banana and some baggie of stale TJ's pita chips that I brought from home. In an ideal world i'd bring a gorgeous salad or pasta dish every day, (I often do!) but on the sad desk banana days I just cut myself some slack and spend $8 on a decent meal.
Most of the time, the only spending me or my husband will do Monday thru Friday is the $25 or so I may have spent during my workweek on food. (his meals are catered at work (jerk!)) I consider this pretty good in the grand scheme of things.
