My interpretation of Adam’s tweets:
I think he was talking about who we THINK we are supposed to be attracted to in our lives. There’s often people we categorize as wrong or right for us, or a picture we have in our head. You think, “this person is wrong for me, I shouldn’t be attracted to them”, or you think it’s just a fluke.
Emma never would have, in a million years, thought she’d be attracted to CAPTAIN HOOK. I mean, to her, it probably even sounds ridiculous, lol. Emma and Captain Hook.
But at the end of the day, you can’t predict who you will fall in love with.
And just because that person doesn’t fit the image of the person you thought you’d end up with, that DOESN’T MEAN that they aren’t the perfect person for you.
