Read the stanza from shakespeare’s “sonnet 18.” shall i compare thee to a summer's day? thou art more lovely and more temperate: rough winds do shake the darling buds of may, and summer's lease hath all too short a date: what is the purpose of these lines? to complain about the intense heat and humidity of summer to persuade a loved one to visit during a warm season to express love by likening a loved one to a nice day to argue that hot weather is more pleasant than cold weather
