How would you explain this sentence?
Father’s explanations made no mention of a lady. She must have cleared out of his apartment in a hurry, to make way for the Easter visitor. On the Q.T., Father is putting on the feedbag with a dame. Dust-colored stockings hang like cobwebs on the bathroom radiator, a lipstick winks like gossip on the bureau. Why would he hide her? Does he not know about Mother and her swains? He should listen through her wall some night, if he thinks his son is unacquainted with bedroom jolly-ups and pig fights.
