Johnny Skeptic and Bobby Believer liked to argue about windows. Johnny would point out how the stained glass of the church distorted the colors of the outside world, whereas the clear glass of a regular window provided a better view. Bobby always countered by saying the colors are so rich and beautiful, and it is a better view of the outside world. Further adding to the disagreement is the fact that the windows were located on different sides of the building, so not only were they looking through different kinds of glass but they were also looking at a different area outside.
One day they noticed a stranger watching them. They didn't recognize him, so they called out: "You there, who are you? Which family do you belong to?" The stranger simply turned around, opened the door, and walked out.
