Heterosexual (Straight) pairings:

·        Hermione Granger/Ron Weasley

    Reasons this pair would work (according to me):

I.                    It is said that boys like girls like their mothers.

a.       Hermione is like Mrs. Weasley (to me)

1.      They were both infatuated with Gilderoy Lockhart

2.      They are both strict with the rules

3.     They both yell at the boys when they get in trouble and every other reason, etc. (when Harry and Ron stole the car)

II.                 They fight like a married couple

a.       If you dont know, said Ron scathingly, Im not going to tell you. (book 4)

1.      Married couples believe that their significant other should always know what has upset them (especially the girls).

III.               Ron gets jealous of other guys

a.       Ron was more mad at Hermione for going to the ball with Viktor Krum than Harry was

1.     Hermione looked at him in surprise. Whats up with you? she said. If you dont know, said Ron scathingly, Im not going to tell you. Hermione stared at him, then at Harry, who shrugged Hes from Durmstrang! spat Ron. Hes competing against Harry! Against Hogwarts! (book 4)
