I saw a western poster-board of what makes a person weirdly happy. And wondered what would be such a thing for me: Something to make one happy, without the involvement, or contribution of any other person ? Have you a happiness thing in your life? Lawn mowing, and finally inspecting the criss-cross pattern on the cut grass always made me happy. If there had been any wiggle in the pattern, I'd be tempted to take the mower back there, run it over the mishap, and straighten the lines again.
