Discuss the character of Hlestakov

Ivan Alexandrovich Khlestakov is described as a rather slight young man with refined features and light, darting eyes. He is in his early twenties, his father supports him, and he has no desire to work. In reality, Ivan cares for nothing beyond gambling, fine dining, and women. He is a bully, a liar, irresponsible, and fully intent upon nothing but his own pleasure.
