[Harry Potter] Why did Hermione Lie?

Why did she lie when she was attacked by the troll in the first book? She just had to say that Ron and Harry went there to warn her, but the troll was already there so they had to fight. It's an acceptable explanation, they wouldn't get in trouble because of that, so why did she lie about it?

She was crying in the bathroom because of something Ron said. Instead of saying that, she claims she was dumb enough to go after the troll intentionally.

It makes her look worse and Ron and Harry look better. Instead of them coming off as bullies who came to her aid out of guilt, they're her friends who protected her from her mistake.
