Yes, for a long time but I admired her and respected everything that I could sort of see in her from a distance, the pillars of her life, the loyalties, the relationships. It all got my interest and also the looks.

The scoreboard said I lost today, but what the scoreboard doesn't say is what it is I have found. Over the last 21 years, I have found loyalty. You have pulled for me on the court and also in life. I found inspiration. You have willed me to succeed, sometimes even in my lowest moments, and I've found generosity. You have given me your shoulders to stand on to reach for my dreams, dreams I could never have reached without you.

It's shocking how little there is to do with tennis when you're just thinking about nothing except winning every point.

I can live with losing, I can't live without taking my chance.
