I lower the gun. I remove my finger from the trigger. My hand trembles. I put the gun back in my pocket.
“Go, Francis. Leave me here. Leave everything here, the war, what happened at the Wreck Centre, leave it all behind, with me.”
Suddenly, I only want to get out of there. The aroma of the soup is sickening and the tenement is too warm. I don’t want to look into his eyes any more.
My hand is on the doorknob when he calls my name. I open the door but pause, making myself wait. But I don’t look at him.
“Let me tell you one thing before you go, Francis. You would have fallen on that grenade, anyway.”
