she got kind of quiet

“Look,” he said. “Don’t it look to you like she would of asked us to stay for supper?” 　“I thought she would,” said Stuart. I kept waiting for her to do it, but she didn’t. What do you make of it?” 　“I don’t make anything of it But it just looks to me like she might of. After all, it’s our first day home and she hasn’t seen us in quite a spell. And we had lots more things to tell her.” 　“It looked to me like she was mighty glad to see us when we came.” 　“I thought so, too.” 　“And then, about a half-hour ago, she got kind of quiet, like she had a headache.” 　“I noticed that but I didn’t pay it any mind then. What do you suppose ailed her?” 　“I dunno. Do you suppose we said something that made her mad?” 　They both thought for a minute. 　“I can’t think of anything. Besides, when Scarlett gets mad, everybody knows it. She don’t hold herself in like some girls do.” 　“Yes, that’s what I like about her. She don’t go around being cold and hateful when she’s mad—she tells you about it. But it was something we did or said that made her shut up talking and look sort of sick. I could swear she was glad to see us when we came and was aiming to ask us to supper.” 　“You don’t suppose it’s because we got expelled?” 　“Hell, no! Don’t be a fool. She laughed like everything when we told her about it. And besides Scarlett don’t set any more store by book learning than we do.” 　Brent turned in the saddle and called to the negro groom. 　“Jeems!” 　“Suh?” 　“You heard what we were talking to Miss Scarlett about?” 　“Nawsuh, Mist’ Brent! Huccome you think Ah be spyin’ on w’ite folks?”
