Mr. Otis in Oscar Wilde's The Canterville Ghost is indeed a practical sort of fellow, and he is a man of action who does not like to sit still and wait when he can be doing something. When his son tries (but ultimately fails) to get rid of the blood stain the library, Mr. Otis locks the library door. He is interested but not afraid.
That practical interest continues. When Sir Simon rattles his chains in the night, Mr. Otis gets up, checks the clock, and is "quite calm" as he investigates the noise. When he sees Sir Simon in all his glowing-eyed horror, Mr. Otis merely remarks, "My dear sir, I really must insist on your oiling those chains." Then he sets a bottle of Tammany Rising Sun Lubricator on the table for the ghost's use and goes back to bed, leaving Sir Simon stunned.
At breakfast the next morning, the family calmly discusses the events of the night before, and Mr. Otis scolds the twins for throwing pillows at the ghost. Then he notes that if Sir Simon will not use the lubricator, they are really going to have to take his chains away from him, because "It would be quite impossible to sleep, with such a noise going on outside the bedrooms."
A few nights later, Sir Simon again makes his noisy appearance, and Mr. Otis pulls a revolver on him and calmly tells him to put up his hands. As the ghost disappears with a horrible laugh, Mrs. Otis reveals that she shares her husband's practical nature and offers Sir Simon a bottle of elixir for his indigestion!
When Virginia comes face to face with Sir Simon and offers to go with him to help him find rest, her family searches diligently for her. Mr. Otis especially springs into action. He goes off to check with the gypsies camping nearby and then off to Bexley, a nearby village. Indeed, Mr. Otis does everything he can think of, unable to be still. Even after he returns home, he cannot just sit. He orders supper and then sends everyone to bed. When Virginia finally reappears, Mr. Otis is rather angry with his daughter, until he hears her story in amazement.
