Garth Callaghan may not have long to live. The 44-year-old father has been diagnosed with cancer three times since November 2011. Although he seems healthy today, doctors told him he only has an 8 percent chance of living another five years.

After his oncologist told him, “You are going to die of this,” Garth thought of his daughter, Emma. Garth has written a napkin note for Emma’s lunch every day since she was in second grade. Whether he offers words of encouragement, love or advice, the napkin notes let father and daughter connect each day.

Emma still has 826 days of school left before she’s set to graduate high school. That’s about 4.5 years of school, and Garth probably won’t be there to see his daughter graduate.

But Garth decided that even if the cancer cuts his life short, he still wants Emma to have a note from him each and every day. He decided to write the last 826 napkin notes ahead of time, and he has just 86 to go.

Meanwhile, Garth has applied for trial treatments in hopes of extending his life.

Whatever happens, Emma will still have adorable memories with her father, like when they attended a father/daughter superhero dance together dressed as Jedis. Emma was mad that Jedis were “not considered superheroes,” but they had fun anyway.
