I tap-tap-tap the window, while my mother smiles and mouths,
Tranquila. I tap-tap the glass, my mother a fish I’m trying to summon.

I tap until a border agent says: Stop. Until a border agent
shows me the gun on her belt. My childhood was caught

on video border agents deleted every three months.
I thought myself a movie star blowing kisses at the children

selling chiclets on the bridge. My cruelty from the backseat window
caught on video—proof I am an American. The drug sniffing

dogs snap their teeth at my mother detained for her thick accent,
a warp in her green card. My mother who mouths, Tranquila.

My mother’s fingers dark towers on a screen for the Bioten scan.
Isn’t it fun? says the border agent. The state takes a picture

of my mother’s left ear. Isn’t it fun? I tap-tap-tap the glass
and imagine it shatters into shiny marbles. A marble like the one

I have in my pocket, the one I squeeze so hard I hope to reach
its blue swirls. Blue swirls I wish were water I could bring to my mother

in a glass to be near her. Friends, Americans, countrymen lend me your ears!
But only the border agent replies, Do you know the pledge of allegiance?

She points to a flag pinned on a wall. I do, so I stand and pledge to the country
that says it loves me so much, it loves me so much it wants to take

my mother far away from me. Far away, to the place they keep
all the other mothers to sleep on rubber mats and drink from rubber hoses.

Don’t worry, says the border agent, we will take good care of your mommy.
My mother mouths, Tranquila. Her teeth, two rows of gold I could pawn

for something shiny, something shiny like the border agent’s gun.
Friends, Americans, countrymen lend me your ears, so I can hear

my mother through bulletproof glass, so I can hear her over the roar
of American cars crossing this dead river by the wave of an agent’s pale hand.
