M: Everyone's having dinner together tonight.
W: That sounds like fun.
M: Can you make it?
W: That's won't be possible. I've got another appointment.
M: When will it be finished?
W: Sometime around seven.
M: Then meet us at the restaurant when you're done.
여기서 언제 마치냐(끝나냐)라고 물었는데
대충 7시라는 의미의 around seven이면 괜찮을거 같은데..왜 sometime이 들어갔나요.ㅠ
sometime의 기능 부탁드립니다.
