Think about something you do that was inspired by your dad or that makes you think of him.
Or a story that brings up something you learned from his illness/passing. Maybe to take a day at a time, maybe that friends and family lift each other up when the going gets rough, maybe that we never really know what others are going through. This story can be upbeat.
It’s easier if you use a short vignette to illustrate this. Show, not tell.
