question:  Why did Mr. & Mrs. Lane agree so quickly to Peggy’s bargain?
context: PEGGY FINDS THE THEATER I Dramatic Dialogue “Of course, this is no surprise to us,” Thomas Lane said to his daughter Peggy, who perched tensely on the edge of a kitchen stool. Mrs. Lane smiled gently and placed her soft white hand on her daughter’s lean brown one. “None of them is as fascinating as acting to me,” Peggy replied, “and none of them is nearly as important to my life.” Mr. Lane, seeing Peggy’s hurt look, was quick to step in with reassurance. 4 Peggy stared at the faded linoleum on the floor for a few moments before answering. 5 “It seems to me, Tom, that Margaret has a pretty good idea of what she’s doing,” Mrs. Lane said. 6 Mrs. Lane patted Peggy’s arm and said, “We won’t keep you in suspense long, dear.

Its musty but clean scent of straw and horses and leather made her feel calm and alive. Peggy stopped first at the bag that hung on the wall among the bridles and halters and took out a lump of sugar as a present.

Peggy had lived all her life here, knew every tree-shaded street, every country road, field, lake, and stream. All of her friends were here, friends she had known since her earliest baby days. It would be hard to leave them, she knew, but there was no doubt in her mind that she was going to do so. It was not any dissatisfaction with her life, her friends, or her home that made Peggy want to leave Rockport.
