W: David, listen to this: "Mr. Gray Smith, 80 years old, is making his first attempt to parachute this Wednesday. Mr. Smith said he had been looking forward to the jump for a long time."
M: Yes. Good for him.
W: I don’t think it is a good idea for Mr. Smith.
M: Why not?
W: Because he is old. In my country, when a person is 80, he is supposed to stay at home and be taken care of
