Collins uses three metaphors to describe the speaker's feelings on turning ten, “a kind of measles of the spirit, / a mumps of the psyche, / a disfiguring chicken pox of the soul.” These metaphors are incredibly complex, using language that would not typically be associated with a ten year old.
The most important thing to eriting essays is that you understand the topic. You can also make an outline of how you want to set up your essay. The thesis statement should consist of telling the reader what the essay is about in only one to two sentences. The thesis is placed in the introductory paragraph. The introductory paragraph shod start out goving facts about the topics you'll cover in the essay. The very last line of the essay should be the thesis. The body paragraphs should start with transitions such as "to illustrate" and a transition for the next paragraph could be "to further demonstrate." The body paragraphs should consist of strong points that always stay focused on the topic. The conclusion paragraph simply wraps up the essay. It gives a braid statement on each of the body paragraphs and, I'm pretty sure it's the first line of the conclusion paragraph where you rephrase your thesis statement.
