[Am] Lover[D], will you l[G]ook at me n[C]ow[Em]?[Am]
I'm already d[D]ead to you
[G]But I'm inclined to exp[C]lain to you what I c[Em]ould not bef[Am]ore
Whatever you [D]didn't do, what you [G]couldn't say
I am s[C]orry that the [Em]worst has arr[Am]ived
For I deserve [D]more
For at [G]least I deserve the res[C]pect of a [Em]kiss goo[Am]dbye
Repeat: (D G C Em Am)
[Am] Tell me[D], do you [G]think of me [C]now[Em][Am]
As I think of [D]you?
For I [G]could not have shaken the [C]touch of your [Em]breath on my [Am]arm
For it has [D]stayed in me as an [G]epithet
I am s[C]orry that the [Em]worst has arr[Am]ived
For I'm on the [D]floor
In the [G]room where we made it our [C]last touch [Em]of the n[Am]ight

I walked[D], because you walked[G]
But I won't [C]probably [Em]get very [Am]far
Sensation[D] to what you sai[G]d
But I'm not a[C]bout to exp[Em]ect something [Am]more
I would not[D] have run off[G]
But I couldn't [C]bear that it's [Em]me, it's my f[Am]ault
I should not[D] be so lost[G]
But I've got [C]nothing [Em]left to [Am]love
Repeat: (D G C Em Am)
[Am] Lover[D], will you l[G]ook from me[C] n[Em]ow?[Am]
I'm already d[D]ead
But I've [G]come to explain why I [C]left such a [Em]mess on the [Am]floor
For when you [D]went away I went [G]crazy
I was [C]wild with the br[Em]east of a [Am]dog
I ran through the [D]night
With the [G]knife in my chest
With the [C]lust of your [Em]loveless [Am]life
I walked[D], because you walked[G]
