He usually takes a nap before work begins in the afternoon. ,F: Then I'll call again in half an hour.
(A) M: Yeah, half an hour. It's reasonable to call him right at 1pm then. (B) M: He just left 10 minutes ago at 11:50. Maybe call an hour later. (C) M: I’m sorry, I didn’t catch that. Would you mind speaking more slowly? (D) M: It's already 1pm now, so he'll be taking a nap in half an hour.
