52. “I almost feel like Ruby is one of my children, but in fact, it is the result of the combined efforts of many people. Without their help, Ruby could never have become what it is.” - Yukihiro Matsumoto, “Matz”, まつもとゆきひろ
53. Language has a grammar. But it also has a culture. It shapes the way we experience world.
54. “Speak a new language so that the world will be a new world.” - Rumi
