The oatmeal did it

    "So there was Blair with oatmeal on the back of his head and oatmeal all over his face, practically a mass of oatmeal, you might say, and then Father smiled a quiet, affectionate kind of smile and said, "I don't like oatmeal." And the whole thing has rather preyed on Blair's mind. He's a little cross about it, I'm afraid. He says I ought to have warned him what he was letting himself in for when he became Father's valet."

    "I don't see how you could have known."

    "Well, Father did tell me his valets never stayed with him more than a week or so,but he said he thought it must be due to this Bolshevist spirit that you see springing up on all sides. It's a great pity, of course, because it has made Blair a little peevish, and I don't think he's very happy."

    "I can quite see how he might not be. Personally, I'd sooner be somebody living in Chicago that Al Capone didn't much like than your father's valet."
