morally permissible

Well I met you at the blood bank
We were looking at the bags
Wondering if any of the colors
Matched any of the names we knew on the tags

You said "see look thats yours!
Stacked on top with your brother's
See how the resemble one another
Even in their plastic little covers"

And I said I know it well

That secret that you knew
But don't know how to tell
It fucks with your honor
And it teases your head
But you know that its good girl
Cos its running you with red

Then the snow started falling
We were stuck out in your car
You were rubbing both of my hands
Chewing on a candy bar
