I actually had a small kangaroo - and I'm not kidding this time. I was holding a small kangaroo, baby kangaroo ... it was very nice to me this time. Do you know what it did afterward? I gave it some milk, and it just spit it all over me. I was like, Is this a thank-you for just being nice and petting the kangaroo? I got milk all over myself. I guess I deserved that from the story last year.

I try to be myself and, of course, be a good role model. I don't really find it hard, but you think about what you do and that other people look up to you.

One day my dad would say, 'OK, if you want to play tennis I can help you out.' And that's how it started. And I had a goal. I wanted to beat my mom first. And my parents and my brother. And that was the ultimate goal.

There's just nothing like playing on Arthur Ashe Stadium. It's truly amazing.

I believe the best in people. I believe if you need a bathroom break you go to the bathroom. If you need treatment, you get treatment. I don't think any rules should be changed.

I used to always be the young one playing without pressure, but I am just happy to be where I am and enjoying my time.

In Denmark lots of people come up to me for autographs.
