context: [Transcriber's Note: This etext was produced from Galaxy Science Fiction December 1956. When he slid under the table containing the drinks, Miss Pringle, who sold millinery, had screamed: "He'll drown!" One out of every three dirty stories started by party attendees had remained unfinished, because each had reminded someone else of another story. "It's all in the spirit of good, clean fun!" cried Mr. Hawkins, the assistant general manager. Mr. Hawkins himself, acting by reflex, attempted to return the portrait to its place until new glass could be obtained. To hear more of it, he said to her: "I'll bet that's been in there ever since the picture was framed. But I remember that my grandmother never bought anything from Hartshorne-Logan because of some trouble her mother had once with the firm. Mr. Hawkins put his arm around Milly in a way that he intended to look fatherly. Two-year-old Sally heard the box rattling. She waddled up on chubby legs and grabbed her mother's skirt. She found scissors in her sewing box, tossed a cushion onto the floor, sat on it, and began to open the parcel. "Now I'll have to write another letter to explain that they should throw away my letter of complaint," she told her daughter. "It's probably the wrong size, too," Ann said, pulling off Sally's dress to try it on. Ann grabbed her daughter's arms, held them above her head and pulled at the dress. When Ann released the child's arms to loosen the dress, Sally squirmed away. She took one step forward, then began to float three inches above the ground. Sally looked scared until she saw her mother's face. She was shaking her head and wobbling uncertainly toward her daughter when the door opened behind her. Sally just—" Sally crouched to jump at her father. A triangular trio of jacks stuck out from one end.
