[Q]: F: How can you be shouting at your grandpa? You can't be so rude! ,M: No, I don't want to be rude to him, but I had to shout so that he could hear me.

So we all respect him. ,F: He looks quite old now. He must be in his seventies, right? ,M: Yes, he is 75 years old this year. ,F: Though he looks so old, he is still in good health. ,M: Yes, of course, he gets up early every morning and does some exercise in our garden. That's why he is still in good health.
(A) F: I'm sorry, I don't understand. Could you say it again? (B) F: Wow, it's amazing your grandfather does cooking every morning instead of doing any exercise.
