The image did not hit me all at once. It came slowly, almost mercifully, as I stepped out through the back door and onto the patio, like my own mind was trying to spare me from seeing it clearly even though it was right there in front of me in plain sight. My son was sitting on the concrete with a paper plate balanced on one knee, not near a chair, not close to the folding tables where the other children were crowded shoulder to shoulder under bunches of red and blue balloons, but off to the side in that strangely deliberate way people create when they want to pretend something just happened naturally. His little legs were folded awkwardly beneath him, sneakers flat against the warm patio, and he was eating with the serious concentration children have when they know one wrong move means their food will slide off the plate and spill into their lap.
