My beloved son, Sean Timothy Nelligan, died at the age of 29 on Father’s Day in 2019. As I was writing his eulogy, I noticed a recurring theme. Each time I wrote down a little story about Sean that I wanted to share with my family and friends, I found myself encouraging everyone to try to live more like him. I told the room of almost a thousand people: “Live like Sean every day and you will make the lives of others so much better, and it will make you feel better also.”
