I'm just so glad we can do that for her, you know? 

Because All Too Well is a EXTREMELY emotional song and its about a very hard time for her and writing it, she was probably like "F*ck you, Jake" 

And when it was still new and the wound was still fresh, it must've hurt like hell to share it, to be that vulnerable.

But over time, and we, as fans, adored the song, and gave it the title 'fan favorite' she was probably like "oh my god, that's really awesome"

And now when she performs it, she still is "F*ck you, jake"

But now it's "F*ck you, jake, you put me through a lot of sh*t. That didn't feel so good. But Guess what? I'm stronger now because of that, so the joke's on you" 

And now when she sings it, I think instead of the hard times, she thinks about how she came back stronger.
