Ronald Weasley always ruins everything. I don't mean making Harry's plans to save the world go horribly askew, I mean he always ruins his chances of getting what he wants. He's always tongue-tied, and when his tongue finally becomes unscrambled, he can't say the right thing. So, yes, it can indeed be agreed that he always messes things up.
Ever since his first year at Hogwarts, he'd fancied Hermione Granger, only he didn't realize it. In fact, the only person to realize that after him was Hermione herself. It wasn't until fourth year when he woke up and smelled the pumpkin juice. Of course, it still took another three years for them to get together because he couldn't manage to put his mouth in its place. The problem now, was that he wanted to marry her. Not going to be easy for a man who can't open his mouth without the wrong words coming out. He accidentally insulted her the first time she asked him out, for the love of Quidditch!
And that's not to mention Viktor Krum and Lavender Brown, to name a few.
It had been terribly unlucky, really. In fourth year, Krum invited Hermione to the Yule Ball first and they just ended up arguing. Again. However, Krum's role in the anti- Ron/Hermione scheme became more potent in their sixth year. Of course, if you were to ask Ron, it was his sister, Ginny's fault. In an argument, she had just happened to let it slip that Hermione had snogged Krum. Of course, that wouldn't have happened if he hadn't walked in on her kissing her boyfriend and gotten all "over-protective-big-brother" But in All honesty it was Ron's fault. Why? His reaction.
You see, instead of just taking it as it was, our dear friend Ronald went and started snogging Lavender Brown to get back at her. All that did was make her go to Professor Slughorn's Christmas party with his Quidditch rival, Cormac McLaggen to make him jealous. Ron just ended up getting bloody'd up by a bunch of birds.
So as you can see, Ron is not exactly the sharpest tool in the shed. The list goes on, but after mentioning Krum, Miss Brown, and McLaggen, I think you get the point. Ronald Weasley is a bona fide idiot…. According to his sister, anyway.
So, how could an idiot of this nature propose to his girlfriend without a glitch- the most likely being her breaking up with him?
Ask his best mate Harry, of course.
After all, Harry was at least a little better with girls than Ron. He didn't make his girlfriend cry all the time! I mean, sure he broke up with her once because he was being a noble git and trying to save her life, but that was four years ago. He's bound to be smarter now! Besides, compared to Ron, he's pure genius. It was obvious;
Ron would get his help from Harry!
