Leslie Harter-Berg's late husband, Ryan, unexpectedly died suddenly and unexpectedly in the early years of the couple's lives. She found a list in Harter's journal, "List of Things to Do Before Death," which she and her sons, Whit and Rory, would check off each year on their father's birthday, March 8. The list was shared after Harter’s most recent birthday and has received over 6 million views on TikTok. The family has since checked off several items on their bucket list, including a trip to an art museum in 2025 and a 3-foot card tower in 2024. HarterBerg also began teaching her sons piano lessons on Harter't birthday.
