Katelyn: Hey, Camden!
Ruthie: Katelyn? (hugs her) You look great!
Katelyn: Santa brought me a new set of lungs this Christmas.
Ruthie: You got a lung transplant?
Katelyn: Thanks to my dad and some of his friends who donated parts of their lung tissue to me.
Ruthie: You look great. Merry Christmas!
Katelyn: A very Merry Christmas. But the merriest Christmas of all will be when they find a cure for CF.
