Jordan:
You're missing the point. That's just rather immature language which really means:
"I didn't know the rule."
I don't think she's denying mistakes at all, nor pretending, nor acting stupid.
She's just a kid, and used kid-like language.
Have you ever heard her interviewed? This is FAR FAR FAR from atypical.
And again, I find it kinda neat. It would be depressing if she was as damn near perfect in language, and guarded with the press, as is our man Tiger Woods.
