My father used to play ice hockey, though not at a high level, and my mother wasn't involved in sport at all, but they were keen that we played some sort of sport. They chose tennis because they thought it was a good sport for girls to play.
I have a different game than most of the players.
It's good to have someone on the tour so close to you - I mean, like, my sister. There is no one closer to me on the tour, so I don't need any other friends than her. We always talk about everything; not only about tennis, but about all the other stuff around tennis.
It's a plus to have a twin sister in the same tournaments.
To beat Serena, she's world No. 1, so it's always tough to beat someone like this. She's never giving up. Even if she's losing, not playing her best, it's always tough to beat girls like this.
I know the world is mean, that there is so much suffering on the planet that none of us can imagine. I often think of those who have nothing, who have to suffer every day, so a winner, a game, set, match will never give me immense joy, only satisfaction.
