Chemistry & Heartache

I stood at the front porch as you drive away
I should have known youd kill me again
But its too late because Im sitting here alone again
I followed your footsteps as youd walk away
To see your face is the reason why Im sitting here
I should have known youd walk away from the inside
I should have known youd kill me again
But I guess Id do it all over again
I should have known youd walk away from the first night
I should have known youd kill me again
Take these memories and well pretend were all the same
Take this chemistry and well pretend were all ok
I should have known you were up to no good
