The X is someone else's star burning inside your mouth

Dear Miss Emily 
by James Galvin

I knew the end would be gone before I got there.
After all, all rainbows lie for a living.
And as you have insisted, repeatedly,
The difference between death and the Eternal
Present is about as far as one
Eyelash from the next, not wished upon.
Rainbows are not forms or stories, are they?
They are not doors ajar so much as far-
Flung situations without true beginnings
Or any ends--why bother--unless, as you
Suggest--repeatedly---there's nothing wrong
With this life, and we should all stop whining.
So I shift my focus now on how to end
A letter. In XOXOXO,
For example, Miss, which are the hugs
And which the kisses? Does anybody know?
I could argue either way: the O's
Are circles of embrace, the X is someone
Else's star burning inside your mouth;
Unless the O is a mouth that cannot speak,
Because, you know, it's busy.
X is the crucifixion all embraces
Are, here at the nowhere of the rainbow's end,
Where even light has failed its situation,
Slant the only life it ever had,
Where even the most gallant sunset can't
Hold back for more than a nonce the rain-laden
Eastern sky of night. It's clear. It's clear.
X's are both hugs and kisses, O's
Where stars that died gave out, gave up, gave in--
Where no one meant the promises they made.
Oh, and one more thing. I send my love
However long and far it takes--through light,
Through time, thorough all the faithlessness of men,

James Augustin Galvin,

X,

His mark.
