I grew up playing in an alley on the south side of Milwaukee.

I like to be with my children - not just quality time, but quantity time. I like to be there in the morning when they're waking up. I like to practice piano with them. I like to be there at supper. I need them as much as they need me. Working is not as important to me as being a mother is.

One of the greatest joys of tennis is having a nice volley and not really keeping score, not really looking at the lines, but just catching up with each other.

We're not playing Milwaukee. We're playing ourselves.

You can make sure your kids make their beds and hang up their clothes and put their dishes in the dishwasher when you're the one calling the shots. So, parenting alone, for me anyway, I think is almost easier, being single.

I grew up on the South Side of Chicago, north Beverly. It was cool, everybody's cool on the block.
