You must know the feeling. Butterflies in your stomach, endless daydreaming, uncontrollable blushing, the inability to say anything remotely cool. That's right. You've felt it. It's a crush, and it's driving you crazy. Crushing has probably existed since the beginning of time and our lives would be much duller without it, but it's never been the subject of much serious study... until now. We've made it easy to compile your own in-depth case file, which will dissect your crush history and reveal your deepest darkest secrets. Using your best forensic skills, you'll draw up profiles, compare symptoms, classify and rate your crushes and fill in the graphs and charts we've prepared for you. Are you a sucker for bad boys? Do you have a thing for braces or greasy hair? Do you avoid hairy men? How many boys have you kissed? How long do your crushes last? And most importantly, do your crushes have a crush on you too? This book is your chance to relive the best (and worst) moments of your imaginary love life, and will make a great gift for swooning romantics everywhere.
