G D Intro

G                                             Em                        D
You arrived at my doorstep, brought in with the tide,
G                                           Em                 D 
It's only that you told them, but I bet you lied,
                                       G                        Em                          D
Oh Mr. Distance couldn't chain you down, but you know he'll try,
G                     Em                             D
Oh I let you in, but you took me inside,

Chorus:
Cadd9                                                Em                                     D
And now I'm falling for you that's the best I can do because I'm clumsy,
G                                       Em                                      D
And I wanted to wait, then I got a taste, now I'm hungry,
Cadd9                                        Em                D
Woo Ohhh Ohhh Ohh Ohhh Ohh Ohh Oh No Oh
D
Oh how you came alive
Cadd9                                        Em                D
Woo Ohhh Ohhh Ohh Ohhh Ohh Ohh Oh No Oh



Polished bottles of wine and a pizza box,
Well you stand there naked only in your socks,
The non-believers they can't stop us now, but you know they'll try,
Lock all the doors, all the windows, just to keep them outside, outside,

Chorus:

And now I'm falling for you that's the best I can do because I'm clumsy,
I wanted to wait, now I've got a taste, now I'm hungry,
I wanted to be what you think you see, but I'm nothing,
Then I caught a glare in your two-second stare now I'm something,

Oh no, oh how you came alive (x2)

Oh Mr. Distance he can't chain you down, but you know he'll try,
Well I let you in, but you took me inside,

And now I'm falling for you that's the best I can do because I'm clumsy,
And I wanted to wait, now I've got a taste, now I'm hungry,
And I wanted to be what you think you see, but I'm nothing, (nothing)
Then I caught a glare in your two-second stare now I'm something,

I'm falling for you that's the best I can do, because I'm clumsy,
And I wanted to wait, now I've got a taste, now I'm hungry,
Woah oh no, oh how you came alive,
Underneath all that you are, all of the candlelight
