Our father came to sleep in our house

Our father came to sleep in our house that night. He carried a small suitcase with a black mourning suit and a pair of polished shoes. Corrigan stopped him as he made his way up the stairs. ‘Where d’you think you’re going?’Our father gripped the bannister. His hands were liverspotted and I could see him trembling in his pause. ‘That’s not your room,’ sad Corrigan. Our father tottered on the stairs. He took another step up. ‘Don’t,’ said my brother. His voice was clear, full, confidant. Our father stood stunned. He climbed one more step and then turned, descended, looked around, lost.
‘My own sons,’ he said.
We made a bed for him on a sofa in the living room, but even then Corrigan refused to stay under the same roof; he went walking in the direction of the city center and I wondered what alley he might be found in later that night, what fist he might walk into, whose bottle he might climb down inside.
