Yeah, I don't ship opposites attract. When I ship, it tends to be from friendship to love, where the people have very strong bonds of trust and understanding and respect for each other. Sometimes there is some bickering. Back when I was a Bones fan and still liked there relationship (so, seasons 1 and 2) Booth and Brennan would bicker over small things now and then, though maybe bicker is the wrong word. They would have a discussion where maybe they didn't agree with each other, but the respect was definitely still very there.

For Harry/Hermione, I remember reading or hearing someone say that the best marriages are ones in which the people can communicate without saying a word. Harry and Hermione definitely have that.
