Great Inventions

Every now and then, many years ago, the family was visited by missionaries. Dad deflected the teaching they were there to teach by showing off an invention of his. One time one missionary was enthralled by the latest invention, the other was standing, watching on the porch with Mom. He finally turned to her as asked if Dad had ever made something for her? She responded, "why sure. He made me a solar clothes dryer." The young gentleman's eyes popped wide. "That is amazing. Did he have difficulty in making that?" "Well, yes, he had to make sure the posts were exactly square from each other with a slight tilt away from the strain of the wires going back and forth between the posts." His expression immediately changed when he looked at the back yard and saw the clothesline.
