Garth Callaghan has been slipping notes written on napkins into his now-14-year-old daughter's lunchbox since early elementary school, but the notes became more precious when he got the fatal diagnoses of kidney cancer.

Inspired by the social movement Because I said I would, Callaghan committed to writing 826 "napkin notes" for his daughter Emma, which means she'll have a daily note up to her high school graduation whether he's alive or not, according to UPROXX.

"Dear Emma, sometimes when I need a miracle, I look into your eyes and realize I've already created one," Garth wrote on one of the many notes.

Every day, Emma saves the notes and puts them in a composition book so she can always have a piece of him, according to an interview on the "Today Show."

Callaghan posts his daily napkin notes on his Facebook page.
