FACT: Ron and I share a deep appreciation for friendship and loyalty. Also, we are both terrified of spiders. Which could be considered a detriment to our relationship, I suppose, but if in our cohabitation we came upon a spider, we would just call my mother the spider whisperer to take care of it. Ron and I also share a love of rodents, as is demonstrated by his devotion to his pet rat Scabbers. (Okay, so it's a hand-me-down pet, and he turns out to be an animagus slash traitor slash Death Eater, but my point is still valid.) I, too, had a pet rat whom I loved dearly. (He was not an animagus, however.) IDEA: If Ron and I lived together, we could have dozens of pet rats who would roam freely about the house and eat all the spiders.
Another bonus: If I was Mrs. Ron Weasley I would be sister-in-law to Ginny Weasley, AKA the BAMF of the Weasley family. Maybe not so much in the first and second books, like when she was doing that whole fugue state thing where she was off smearing chicken blood on walls and whatnot without remembering it, but Ginny really grew into a kick-ass witch... Unlike some know-it-all drama queens *cough* Hermione *cough*
Well, I have successfully wasted fifteen minutes simultaneously not studying for my Spanish midterm and contemplating my marriage to a fictional wizard. I'd call that a win.
*I should note that, had Cedric Diggory survived beyond book four, things might be different. Polygamy would probably be involved.
