There was really plenty of room for the two to pass each other, but Steve was not in a frame of mind to give way to anyone and the result was that the other chap received the full force of Steve's shoulder.
"Who are you shoving ?" demanded an angry voice.
Steve turned and confronted Eric Sawyer.

"Don't take all the room if you don't want to be shoved," answered Steve belligerently.

Eric was accompanied by a younger fellow, who instantly withdrew to the safety of the further side of the hall.

"You're too big, anyway," continued Steve.
Tom and the others, at his heels in the open doorway, gasped and stared at Steve in amazement.

Eric's countenance depicted a similar emotion for an instant, and I think he, too, gasped.
