Example from Literature

Joe, who had ventured into the kitchen after me as the dustpan had retired before us, drew the back of his hand across his nose with a conciliatory air, when Mrs. Joe darted a look at him, and, when her eyes were withdrawn, secretly crossed his two forefingers, and exhibited them to me, as our token that Mrs. Joe was in a cross temper. This was so much her normal state, that Joe and I would often, for weeks together, be, as to our fingers, like monumental Crusaders as to their legs.

— Charles Dickens, Great Expectations
