Betsy is suing her dоctоr, аrguing thаt the dоctor did not exercise the required level of cаre when he operated on her knee. Her husband testifies in her case, describing the difficulty that Betsy had moving around in the weeks after the surgery. At one point during his testimony, he testifies that “two months after the doctor performed the operation, Betsy could still not walk up the stairs of our home.” The doctor’s attorney cross-examines the husband and asks him whether it is true that two months after the operation, he had dinner with a friend and he said: “Betsy is really recovering well after her surgery. She can go up and down the stairs at our house with no problem.” Can the doctor’s attorney ask her this question?
