Listen, I had a really bad incident with this shit, so I really know what I'm talking about here.... basically, when she's 15, she's off limits. Wait until she's 16. Even if you're not going to have sex, because the minute you 'accidently' get lost in passion, you're putting yourself in jail also police can charge you with all sorts of fucked up laws like enticing a minor, which means the minute you kiss her, you're 'enticing' her. What's a year anyway if you REALLY think you like her and you're already friends? I dunno, that's just my opinion.
