"A lot of parents will let their kids beat them in sports to encourage them, but she wouldn't do that. That wasn't part of her parenting philosophy."—Robert F. Kennedy, Jr.

"We learned sports from Mummy. She taught us to ski. She taught us to play football. She made sure we weren't going to sit around and feel sorry for ourselves." —Kerry Kennedy
