Even if they hadn’t already known the reason for our coming, they could not have failed to notice my shaved head and the mourning stripe across my face, and Captain Hetny’s. These people didn’t know us, quite possibly didn’t know who had died. We represented the forces that had conquered them, torn them away from their home world to labor here. They had no reason to care for our feelings. They had no reason to think that either of us knew enough Delsig to understand the words.
