Step-by-step explanation:
The informal essay is an essay written for pleasure. Its purpose is to help you organize your thoughts on a specific topic, to reflect on readings, and to express different points of view. It can still be informative and convincing, but you're allowed to write it with less formal expressions. As this type of paper is not formal, you can find personal observations, opinions, or points of view. The main thing is that this example is written in a relaxed manner, but it adheres to a particular structure. Short informal essay examples usually include the personal contact, and not the academic writing flow.
