"I was coming down from the theatre one night about a week later, and I thought I'd look in at the 'Isle o' Man' for a drink before going aboard. There was a good few in there, Greek and Norwegian skippers; and a Belgian engineer was sitting across from me with old Croasan. The piano was going with _Little Dolly Daydream_, _Pride of Idaho_, when in comes Rosa with her tray. To get past she had to squeeze between old Croasan's table and the piano, and I saw him take hold of her waist. She was hampered by the tray, and he was pulling her down on his knee. "I don't think it was all gallantry that made me do what I did. I'd never been a whale on that sort of thing. I'm not built on those lines. I think it was a feeling that has always possessed me very strongly when I see an old man with a young woman--disgust. To me it is a horrible sight, the lust of an old man. You can argue as long as you like, but that is one of my fixed eternal prejudices. I feel sick when I see an old man giving way to it. I feel that somehow or other he is debasing humanity. That was the real reason why I jumped up and went over to Croasan. "He looked up at me as I stood over the table. I could see the crease in his cheeks, the sag under his eyes, and the grey roots of his dyed moustache. He looked up at me as I raised my hand. 'Let her go,' I said, shouting at him above the jangle of the piano, 'let her go, Mr. Croasan.' He was holding her down on his knee. "'Mind your own affairs!' he says to me, showing his teeth, great dirty yellow fangs; 'Is she yours?' he says. The Belgian engineer sitting near him laughed at this and looked up sneering at me. 'Let her go,' I said again. 'Rosa's a friend of mine,' says he, still holding her. Just then I saw Rebecca's head over the piano, and as I looked down again I saw a peculiar expression on Rosa's face. Her eyes were on me and she seemed to be thinking 'What are you waiting for?' It all happened, you know, in two or three seconds. I waited no more. I put the flat of my hand across Croasan's mouth, hard. He jerked back to avoid it, and the tray that Rosa was trying to set down on the table, so that she could get at him with her nails, went all over him. The old woman came round the piano and saw him. Croasan started up and I hit him again, and he fell over the Belgian. "At first I thought I was in for a big row. But Croasan had more experience than I had. He'd been in rows before. When he started up it was not to hit me, but to get out. He crawled under the table between the Belgian's legs and ran to the door. The others were crowding all round me, arguing and shouting. The young chap at the piano was standing up and looking over the top, and Rebecca was trying to calm them. 'Easy, gentlemen!' she kept on calling. Rosa had disappeared. Then the Belgian jumped up and shouted, 'Ee interfere wis my frien'!' pointing at me, and marching out.
