Tuxedo a piece of clothing you wear to a fancy place
The excerpt from Lord Byron's Childe Harold's pilgrimage that most clearly describes a state of alienation is the third one:
C. But soon he knew himself the most unfit / of men to herd with man.
He says here that he isn't the type to be around other people, which is why he prefers to be around himself only. Although that doesn't mean he doesn't like or want to be around other people, it is just that he doesn't know how to and is thus alienated.
The goal of a satire is to criticize or ridicule somebody or something (an action, a situation, a behavior). For that reason, it usually features sharp and mordant ideas. In this excerpt from the <em>Adventures of Huckleberry Finn</em> by Mark Twain, Huck, the main character, is describing one of his encounters with the severe Miss Watson, his guardian's sister. In it, Miss Watson, who wants Huck to accept religion at all cost, is telling him to pray everyday, and, as a reward, he will get what he asks for. However, Huck, tired of not getting it (hooks for his fish-line), harmlessly asks Miss Watson, to her dismay, to do it for him, since, so he believes, she may be luckier and gets what he has asked for in his prayers. Miss Watson's livid reply and Huck's unaffected comment emphasize the mocking nature of the theme in this excerpt.
