A woman has just returned from seeing her doctor for her annual physical. Her husband asks her how things went. “Everything was fine” she replied. The following morning he notices her sifting through a cup of sugar, but thinks nothing of it, figuring she was planning on doing some baking. The sifting ritual repeats itself that evening.
This continues for a couple of days, where the woman gets a cup of sugar, sifts through it, and returns it to the larger sugar bowl that she got it from. With curiosity getting the better of him, the husband asks the wife why she keeps on “playing” with the sugar. “I am not playing with the sugar silly, I am following my doctor’s instructions to check my sugar twice a day” she replied innocently.
