Then Mark Twain went to sleep.Later,when he woke up,it was night-time and the train was in Paris already.He realized at once that the conductor had forgotten to wake him up at Dijon.He was very angry.He ran up to the conductor and began to shout at him.“I have never been so angry in all my life,”Mark Twain said.
