1784, five years before Washington became president of the United States, he was just 52 years old and almost lost his tooth. He asked the dentist to implant nine teeth in his mouth, and all nine teeth were actually pulled out from the mouths of his slaves. This is what historians have just discovered in archaeology. Washington, the hero who once liberated slaves, suddenly collapsed in our hearts, and we seemed to see the stain on the holy robe. But if you think about it carefully, it is not surprising to put yourself in the social background at that time. Yes, we regard a person as a saint because we don't know him well enough, so we can only look at him from a distance, paint him with various colors in our hearts, and then lower our heads to increase his height. In this sense, we should thank Washington for its imperfection.
