William Shakespeare wrote 154 sonnets. Sonnet 18 is perhaps the best known of all sonnets. Sonnet 18's purpose focuses on the loveliness of a friend or lover, begins with a rhetorical question comparing them to a summer's day. He also talks about the pros and cons to the weather, from an idyllic English summer's day to a less welcome dimmed sun and rough winds. In the end, it is the poetry that will keep the love alive forever, defying even death.
