His face was trapped in the ceiling tiles above my computer. I stared at the roof, feeling the bile rise up in my throat. I hadn’t noticed it at first. The line on the bottom could have been anyone’s smile, and the two black dots among the white plaster could have been anyone’s eyes. But after he had leaned over my desk the first time, shouting at me, I stared at the ceiling tile straight afterwards and ever since pictured the outline of his face every time I looked at it.
