Read it through once

Newland Archer was a quiet and self-controlled young man. Conformity to the discipline of a small society had become almost his second nature. It was deeply distasteful to him to do anything melodramatic and conspicuous, anything Mr. van der Luyden would have deprecated and the club box condemned as bad form. But he had become suddenly unconscious of the club box, of Mr. van der Luyden, of all that had so long enclosed him in the warm shelter of habit. He walked along the semi-circular passage at the back of the house, and opened the door of Mrs. van der Luyden's box as if it had been a gate into the unknown.
