I never met Una, but we communicated briefly shortly after we began following one another on Twitter. Una said she was "chuffed" that someone so far away -- I'm in the San Francisco Bay Area -- was following her. I could easily have said the same thing to her. Una was clearly brave and compassionate. She freely gave that most precious gift, her time, toward helping others. It's a tremendous legacy. My thoughts and prayers are with her family, friends, and all who knew and loved her. Peter
