내용이해ㅠㅠ(대충만요약해주셔도감사해요ㅠㅠ)

a small town lawyer was interviewing a witness, an elderly woman who had lived in the town her whole life. while questioning her, he casually asked, “do you know who i am?” “i certainly do,” the woman replied. “i used to babysit you. you were lazy then, and you’re a liar now.” the lawyer was shocked. to shift the courtroom’s attention from himself, he pointed at the other lawyer and asked if she knew him. “of course, i do,” she replied. “he drinks too much and his wife must be the stupidest woman in town.” the judge suddenly stopped the trial and called both lawyers over. “you shouldn’t have asked her that sort of question,” he said “and if you ask if she knows me, i’ll throw you in jail!”
