Funny, I loved it!
Haha, love that last line!!
Haha, I love your first stanza!!! It's hilariously funny, and it is absolutely true. For so long, Ginny had been an outsider - the girl that was in the Chamber of Secrets and one year younger than a lot of people. But in the end she got Harry and she had a right to be proud. Your rhyming is nice, and it is very true and funny.
I have to admit that I do not quite understand the second stanza. Yes, Harry asked her to the dance, and yes she twittered and giggled, but why did she lose the chance at romance? Wasn't it Harry who didn't want to dance with her.
The rest of the poem is good. I like it. It makes me actually feel good for Ginny, and made me feel like she deserved harry. As a STRONG Harmony shipper, this is something that only a really good author with an excellent way with words an achieve. So I commend you.
Well I wasn't expecting this type of poem when I clicked on it. But it was witty, funny, and original and I loved it! The ending part was the best! :)
Last line's priceless. :D
