From The Adventures of Huckleberry Finn by Mark Twain

Well, three or four months run along, and it was well into the winter now. I had been to school most all the time and could spell and read and write just a little, and could say the multiplication table up to six times seven is thirty-five, and I don't reckon I could ever get any further than that if I was to live forever. I don't take no stock in mathematics, anyway.
At first I hated the school, but by and by I got so I could stand it. Whenever I got uncommon tired I played hookey, and the hiding I got next day done me good and cheered me up. So the longer I went to school the easier it got to be. I was getting sort of used to the widow's ways, too, and they warn't so raspy on me. Living in a house and sleeping in a bed pulled on me pretty tight mostly, but before the cold weather I used to slide out and sleep in the woods sometimes, and so that was a rest to me. I liked the old ways best, but I was getting so I liked the new ones, too, a little bit. The widow said I was coming along slow but sure, and doing very satisfactory. She said she warn't ashamed of me.
