"you may as well stop making a fool of yourself over warren mcintyre. he doesn't care a snap of his fingers about you." for a tense moment they regarded each other—marjorie scornful, aloof; bernice astounded, half-angry, half-afraid. then two cars drove up in front of the house and there was a riotous honking. both of them gasped faintly, turned, and side by side hurried out. all through the bridge party bernice strove in vain to master arising uneasiness. she had offended marjorie, the sphinx of sphinxes. with the most wholesome and innocent intentions in the world she had stolen marjorie's property. she felt suddenly and horribly guilty. after the bridge game, when they sat in an informal circle and the conversation became general, the storm gradually broke. little otis ormonde inadvertently precipitated it. "when you going back to kindergarten, otis? " some one had asked. "me? day bernice gets her hair bobbed." "then your education's over," said marjorie quickly. "that's only a bluff of hers. i should think you'd have realized." "that a fact? " demanded otis, giving bernice a reproachful glance. "there's a lot of bluffs in the world," continued marjorie quite pleasantly. "i should think you'd be young enough to know that, otis." "well," said otis, "maybe so. but gee! with a line like bernice's—" "really? " yawned marjorie. "what's her latest bon mot? " no one seemed to know. in fact, bernice, having trifled with her muse's beau, had said nothing memorable of late. "was that really all a line? " asked roberta curiously. bernice hesitated. she felt that wit in some form was demanded of her, but under her cousin's suddenly frigid eyes she was completely incapacitated.
