She had called him down the second time she walked out with him, because he had gone along on the inside, and she had laid the law down to him that a gentleman always walked on the outside--when he was with a lady.

And Minnie had made a practice of kicking his heels, whenever they crossed from one side of the street to the other, to remind him to get over on the outside.
