Rule number one - It's only supposed to last for a week.... Ethan is a cocky, arrogant jerk. He's always been that way. I'll never understand why girls trip over themselves just to be with him. Don't they realize he's going to ditch them in a week?

I was never supposed to fall in love with my stepbrother. I never intended to. It just sort of happened. Rule number four - You can change your mind, too, Ethan. We can't. We're done. This girl lives in the same house as me. Her bedroom is just down the hall. It barely takes 20 seconds to go from her room to mine, and yet it's an impossible distance now. She might as well be on the sun.

I thought I was a good girl, but then why do I love hearing all of the naughty things he says he wants to do to me? Rule number three: You can change your mind, Ashley. Not just now. Whenever. I could tell Ethan that the only thing I'll regret about this is that we only have a week together. Except I can never tell him that. I need to stop. I need to understand that this is a temporary situation, and that I'll never have it ever again, because no matter what, it won't work out, whether I want it to or not.

I don't know when it happened. I didn't think it'd ever happen. I can't lose her. I can't even imagine losing her. Rule number six: This is supposed to be fun. Understand? He's my bad boy and I'm his good girl. And, yes, he's my stepbrother and I'm his stepsister.

Rule # 12: You can tease me, Ethan, and we can play, but you can't be mean to me. I need to know that there's more, that this isn't wrong, that you feel the same way I feel.... I never wanted to hide this from you, Dad. It wasn't about that. It wasn't that I was ashamed or thought I was doing anything wrong, but I didn't think you'd understand, and I wanted to be with Ashley. I want to keep being with her, and whenever I thought about telling you and then thought about you getting mad about it...well, yeah, that's it.
