Used To

Does the pain remain when the head is turned
And the body wants a way you used to know
Does nausea ensue when you chance upon the memory
of someone you used to know
Does one thing crease when the pulse is strong
But the response is weak, you used to know

I'll just lay down guidelines in front of me
It said never do the things you do to me

I'll give you an example - typically
it's less complicated than it simply should be
