You know when sometimes you meet someone so beautiful and then you actually talk to them and five minutes later they're as dull as a brick? Then there's other people, when you meet them you think, "Not bad. They're okay." And then you get to know them and... and their face just sort of becomes them. Like their personality's written all over it. And they just turn into something so beautiful. - Amy Pond | The Girl Who Waited, Doctor Who.
