A Mother's Intuition.
The first thing I notice about Ginny and Harry is that they don't talk as much. Last summer, all they did was talk and talk and play Quidditch, but then talk more. They do speak a little, words of welcome and good-bye, and that's about it.
The second thing I notice is their blush. Harry blushes when he's alone with Ginny, and Ginny does the same. They were completely comfortable together last summer, and now they can't seem to even look at each other without turning crimson and looking away.
The third thing I notice is their face. Whenever Harry seems down, once Ginny comes into the room, he face changes. First, into surprised, then a grin, and he seems more talkative. Ginny is the exact same. Her smile is wide and a little brighter when he walks in.
The fourth thing I notice is the 'I'm sorry" phrase. Whenever Harry interrupts Ginny reading, he apologizes quickly before bolting out of the room. When Ginny walks into Ron's room without knocking, and finds Harry, she says 'I'm sorry', before leaving quickly. They say it too much.
The fifth thing I notice is the unplanned accidents. Whenever Ginny is in the room, Harry is prone to knocking things over. He even put his elbow in the butter dish, once. Ginny accidentally tripped and fell down the last stair when she peeked into the bathroom, to find a shirtless Harry.
The sixth thing I notice it the fake 'accidents'. Like when Harry tripped Ginny, by accident of course, and caught her in his arms. Or when Ginny asked Harry if he could help fold laundry. What her true intentions were, I can only guess, but I have an idea that it involves a bra being 'accidentally' put into Harry's boxer shorts.
The seventh thing I noticed was the feeling of sadness. Of course, with Alastor, it was sad, but Ginny seemed miserable when she stepped off of Hogwarts Express. Even with Dumbledore's death, she shouldn't of shunned everything that had to with love. As I arranged her Hogwarts trunk, I found a notebook. First, it said 'Mrs. Dean Thomas' but then it was scratch off, and replaced with 'Mrs. Harry Potter' but that in turn was scratched off too. By then, it was clear.
My name is Molly Weasley, and I believe Harry Potter dated my Daughter, Ginevra Weasley, and then dumped her.
