A Boy in a Bed in the Dark

Born with a cleft palate,
My two-year-old brother,
Recovering from yet another surgery,
Toddled into our bedroom
Toppled a tower of blocks
That I had patiently built
And in a five-year-old's fury
I grabbed a fallen block
And winged it at him
Ripping open his carefully reconstructed lip.
The next hours were gruesomely compressed
Ending with a boy in a bed in the dark
Mute with fear
Staring out into the hallway with horror
As the pediatrician went in and out of the bathroom
With one vast blood-soaked towel after another
Shaking his head worriedly.
My brother's howls
And my parents' cooed comfort
Became the soundtrack to this milky movie
That plays
In my darkest theatre,
The one that I sidle past each night
With a shudder
And a throb in my fist
