I know that (clause), but...

This is a good phrase to use when you're trying to persuade someone. You show that you understand their possible disagreements before you express your own point. For example:

Listen - I know it's none of my business, but you should probably apologize to her.

I know you're busy, but can you help me out with this?

You can use the word "that", or leave it out in more casual spoken English.
