For one second, that concentration almost disguised it. If you only glanced, if you kept moving, if you had trained yourself to overlook small humiliations because recognizing them would force you to do something, you could almost tell yourself he was fine. You could say he had chosen to sit there. You could say kids do not care where they eat. You could say there were bigger things in the world to worry about.

But I looked closer, and once I did, I could not unsee any of it. Not the empty space between him and the table. Not the way the other children were laughing with their knees tucked under white plastic chairs rented from the church down the road. Not the bright party tablecloths weighted down with plastic cups and bags of chips and trays of frosted cupcakes, decorations that stretched neatly across the yard until, all at once, they did not. There was a clear border where celebration ended and my children began.
