Give her the book back, slip a note in it saying "[i]Valentines Day: 7pm at *nice restaurant near you*[/i]" ("[i]wan sum fuk" optional[/i]) Possible outcomes: 1) She turns up: 1.1) You spend the rest of your lives together 1.2) You date for a bit and then break 1.3) You get sum fuk and that's it 2) She doesn't turn up: 2.1) It's dead awkward forever between you two 2.2) There's no awkwardness as she hasn't read the note 2.3) Unfortunately you were wrong in her liking you and everyone in school knows. [spoiler]Nah that's a wet way to play it. If I were you I'd give it her back and spark up conversation. Get to know her a bit and get chatting, maybe hang out and breaks and then finger her [/spoiler]
