D    
Last night I smoked a cigarette
Gmaj7                         Em
My dad would have been so upset

And I just stood there like a ghost

Maybe you don’t really want me there at your birthday party

I’ll be there in the corner, thinking right over
Gmaj7                    Em
Every single word of the conversation we just had

So why am I like this? Why am I like this? Why am I like this? Why am I...

Gin and tonic from a can to ease the pain

I never asked if she was OK

She just got up and walked away

             G5
Never in the moment, never giving enough
Bm                 A                             Em
  Let’s go out and shout the words we never said

I got my mistakes on loop inside my head, inside my head
