This document discusses the differences between falling in love and having a crush. It notes that love develops gradually over time while infatuation occurs suddenly. Love accepts the imperfections of one's partner, focuses on more than just physical attraction, improves one's mood, and can withstand arguments, whereas infatuation is based on an idealized image and focuses only on physical attraction, is draining, and glosses over arguments. The document instructs students to describe what happens when one falls in love compared to having a crush, using the grammatical structure of "if + subject + simple present + future with will, may, or might."
