What kinds of things do you have to read carefully in your first language?

For me, I have to read contracts and legal documents very carefully, especially when I'm dealing with work-related agreements. It's crucial because a small mistake can lead to misunderstandings or even financial issues. Just last week, I reviewed a freelance design contract for a project, and I spent extra time checking the payment terms to make sure everything was clear. It's not the most exciting reading, but it's definitely important.
