I will say that I experienced sadness when I stopped at the Walmart for yogurt on the way back to the Days Inn.
They have freezer/refrigerator cases in the food center whose lights have been equipped with proximity switches.
The cases lit up so hopefully as I approached, displaying their wares to my dully surprised gaze, but I passed by
without stopping, for it was late and I was tired and I had no use for most of those things anyway.
Still, I felt obscurely bad for disappointing their nonexistent little robot hearts.
