Would you mind repeating that for me?
If I leave my number, will he call back today?
Our sales manager has been called away on urgent business.
All of the staff went to the trade show last month.
I would have liked to drop by last week, but I was too busy.
Shall we say the 11th at two o'clock?
Urgent business has priority over everything.
Particular means specific or precise.
Advertising helps increase sales.
Away on business means work-related travel.
