Urgh, yes. Dear Ginny: you look like my dead Mum, and I miss her so much. Plus, I'm crazy about your family, and if I marry you, I get to have YOUR mum and dad as MY mum and dad. Two mums! Hurray! Let's breed!
Ack, ack, ack. I've read some really lovely fanon Harry/Ginny stuff (often in the context of Snarry, actually!), but it just doesn't work for me as it stands in the books. That girl needs fleshing out.
