In history class, the teacher taught said the Magna Carta was signed in 1215 and to write an essay on it. A student handed in his work with "The Magna Carta was signed in 1215" written 150 times. The teacher asked the boy, "Why did you write this?" The boy replied, "Because you always say that history repeats itself!"
One fundamental lesson our teacher has taught us in History class while talking about the Civil War was never to take victory for Grant-ed.
