Why did Harry meet Sally??

I donno if I have to agree with Harry or Sally. In case you are wondering what I'm talking about, I just saw the flick "When Harry met Sally". Harry aka Billy Crystal keep saying that a guy n a girl can never truly be friends. Sally aka Meg Ryan, obviously, keep telling otherwise - its not all about Love and the Act.

I kept looking within myself trying to figure out who to agree to. You see, I have my reasons.

Maybe, I just won't be able to figure this one out.

"Harry, would you wish you never met Sally then?"
