Imagine the following scenario:
Person A: I love this movie so much! The story is so beautiful!
Person B: Well, the story isn't true.
Now, person A has a few options in how to follow the conversation:
- Who cares if it's true. It's a nice story!
- Who cares if it isn't true. It's a nice story!
- Who cares that it isn't true. It's a nice story!
I reckon it's correct to use isn't, as the negative is used in the original statement, but I'm not exactly sure how if versus that changes the meaning.
Can anyone shed some insight on this?
