Basking in the beauty of the day, I sit and relax in the park, only to find my mood dampened by the mud that has dirtied my favorite boots from the damp grass. Fortunately, I have my little puppy with me for his hour of exercise, and I promptly summon him to attend to the task that suits him best. He comprehends that my boots require cleaning and polishing, and dropping to his knees, he begins to use his tongue with expertise. The filthy soles immediately blacken his tongue, yet he doesn’t seem to mind, and in the meantime, I arrange the evening by exchanging messages with my friends.
