A sentence is a group of words that has a subject and a verb and forms a complete though. It starts with a capital letter and ends with a punctuation mark (a period, a question mark, or an exclamation mark). <em>The baby</em> (subject) <em>cried </em>(verb). It expresses a complete idea. Fragments are dependent clauses or phrases.
The story is trying to convey the message that being attracted to someone, or being infatuated, is not the same as true love. The teenage girl feels excited and happy to have someone care for her, however, the boy is not serious about her. He wanted to "pick her up" but had no intention of ever turning this passing flirtation into a serious relationship. The story also suggests that not being able to distinguish between these two different types of attention can cause a lot of heartache and confusion.
The words the author choses are those that resemble the speech of a teenager. This allows us to sympathize with the girl by making it easier to imagine the types of thoughts she is having. The author also uses some rhetorical devices such as anaphoras (the repetition of words at the beginning of neighbouring clauses), similes and metaphors. These use of words contributes to the theme of confusion and pain that comes from confusing superficial flirting with serious attraction.
