Have you ever had to call something off?
People like to make plans. But those plans don’t always work out. If you plan something, there’s always a chance you will have to call it off.
When you call something off, you cancel it. You can call off an event, like a party. “We had to call off the party at our house this weekend because of a family emergency.” You can also call off an agreement you have with someone. “The business partnership was no longer profitable, so she called it off.”
