The Day Vacation At Barbados - 1266 Words

This summer my family and I had the chance to embark on a seven-day vacation to Barbados. Tucked just above Venezuela, the island country known for its rum, mahogany, and flyin’ fish is situated three degrees north of the equator. During our stay, we tried to avoid the tourist traps, seeking authentic cuisine and local lifestyle, hoping to experience Bajan culture in its purest form. Wherever I go, be it down the street or across the globe, I crave authentic and more importantly honest food. This is hard to find. I’ll often ask these questions to locals — â€Å"Where do you go to eat?, â€Å"Where do you go when you get off work?†, or â€Å"Where do you take your family?†. These questions usually yield restaurants that most travelers never reach,†¦show more content†¦He sat down, asked us where we were from and created small talk.

He informed us that it was indeed real aloe, that it was all natural and would â€Å"cure the burn, mon†. After his stunt, he handed us the bottle and said â€Å"there ya go, now who’s in charge here?† I pointed to my dad. Billy said that will be B$20. (The Barbadian doll ar (B$) is worth exactly  ½ of the USD and merchants accept both currencies). My dad said how about B$10. Billy countered with B$15 and we agreed. We really didn’t want the aloe, we didn’t ask Billy what he was selling, but for some reason Billy singled us out. Immediately following our encounter with Billy, we were approached by an unnamed fellow, who I noticed earlier seemed to be smoking some of the local grow. He once again asked us where we were from, then proceeded to give us small pamphlets and placed colored silicone bands on our wrists. We thanked him for the wristbands, continued the conversation for a bit more, and then began to proceed with our walk. He halted us, once again asking us who was in charge and stating that the bands he just gave us cost $30 USD. My dad gave him a dollar, my parents

The author will try to make meaning of an experience to express their intent in a more meaningful manner to the audience.

The writer is constrained to explain the knowledge related to only a single topic in informative stories. Persuasive – changing the audience’s mind Persuasive writing involves taking a position on a debatable issue to convince an audience one way or the other about that controversial issue. In persuasive writing the writer presents his or her opinion and tries to convince the reader to agree. Persuasive writing is also known as presenting an argument because the writer uses words to convince the audience that their opinion in which they are writing about is correct. Persuasive writing, especially in short stories, is very commonly used. Persuasive writers employ many techniques to improve their argument and show support for their claim. Students understand that persuasive writing is audience-centered; the needs of the intended audience are the most important consideration. Conclusion – I am proposing that the use of force, even if it causes pain, is ethical and sometimes necessary in order to help someone for their own good.

This article examines the topics of increased crim Essays

This article examines the topics of increased criminal activity as a result of the prohibition act that was passed in the 1920s. Americans resorted to criminal activity in hopes of making money which contributed to the already increasing rate of organized crime and violence that plagued the country. Hypocritical governments and corrupt police were prone to taking bribes and gang wars were common, most notably the gang wars revolving around the infamous Al Capone. This article is a credible source as it was written by Rodney Carlisle a professor at the Rutgers University in New Jersey. Carlisle has a PhD in history from the University of California and earned an AB in history from the prestigious Harvard College which proves that Carlisle has an extensive knowledge of American history, the 1920s included. This article is immensely useful when it comes to studying the themes of The Great Gatsby. The article covers what life was like back in the 1920s and just how much crime and bootleg ging influenced Gatsbys fortune. The concept of the American Dream is as stated: The American Dream is set of ideals stating that in the United States freedom includes opportunities to obtain prosperity, success, and upward social mobility through hard work no matter what an individuals racial, religious, or economic background is.. Based on this ideology, the American Dream is all about working hard to be able to achieve prosperity and success. However, bootlegging and gang violence are nowhere near this ideology, in fact they are the twisted perversion of the American Dream that is portrayed by Fitzgerald in The Great Gatsby. Fitzgeralds portrayal of the American Dream with the characters in the novel would have to be the extravagantly hollow, upper class individuals who spend tremendous amounts of money in hopes of enhancing their personal image or persona that they wish the world to view them with. The article looks at this indirectly as most gangsters who were bootlegging at th e time, such as Al Capone made a fortune of money, much like Gatsby. Capone used this money to purchase elaborate cars and furniture similarly to how Tom and Gatsby spend their money in order to look more wealthy and achieve more status in hopes of achieving their ultimate dream. Fitzgerald also portrays how the American dream has degraded and become unachievable for the poor by including characters such as George Wilson as these characters are broken from the long hours of labour they endure.
