bernice bobs her hair
by f. scott fitzgerald (excerpt)

all through the bridge party bernice strove in vain to master a rising 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? " someone 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.
bernice's ears burned as she tried to think up an effectual come-back. in the face of this direct attack, her imagination was paralyzed.
"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.
"i don't know," she stalled.
"splash! " said marjorie. "admit it! "
bernice saw that warren's eyes had left a ukulele he had been tinkering with and were fixed on her questioningly.
