It was just six seconds long, but the viral TikTok said it all: a dad in a cap and gown, stunned and smiling as he spotted his family in the crowd. The text overlay read, “My dad: ‘you guys don’t have to come to my graduation, I know it’s a long drive for you.’ My dad seeing that we all showed up anyway.” “My dad’s always trying to make sure no one feels inconvenienced,” Ashtyn Bradshaw tells PEOPLE. “He told us not to worry about it, but there was no way we were going to miss that.” Jon, a father of four and now a proud grandfather, had spent years quietly working toward a milestone that meant the world to him. He was graduating with a master’s degree in biblical leadership from Western Seminary — an accomplishment that came late in life, but not too late. Ashtyn says she didn’t even know the ceremony was happening at first. “He was kind of quiet about the whole thing,” she says. It wasn’t until her sister mentioned the graduation was coming up that it fully hit her. “I just looked at my husband and said, we’re going,” Ashtyn recalls. The family lives in Olympia, Wash., about two and a half hours from Portland, Ore., where the ceremony was held. But the decision to make the trip wasn’t even a question. “He’s been to all of our graduations, every big thing in our lives,” Ashtyn says. “Of course we were going to be there for his.” What made the moment even more touching was Jon’s complete surprise. “I just didn’t want them to feel obligated,” Jon tells PEOPLE. He wasn’t trying to downplay the importance of the day. In his mind, he was just being practical. “They’ve got kids, jobs, a million things going on,” he says. “I never want to put any extra stress on them. I just wanted to be considerate.” That quiet act of thoughtfulness is exactly why Ashtyn felt compelled to film the moment. Her TikTok, posted with the caption “no because why is he so precious in his cap & gown,” went viral overnight. “I didn’t expect it to blow up,” she says, laughing. “I just wanted to share how proud I was of him. Honestly, I was just sitting there thinking he’s too cute in that gown.” Ashtyn says the video sat in her drafts for a couple of weeks because she thought it might be “weird” to post it. But once it went live, the response was instant — and emotional. “People were saying things like, ‘He’s our dad now,’ and it was just really sweet,” she says. “It hit people in a way I didn’t expect.” Jon, who jokes about being “too old for TikTok,” didn’t even know the video existed at first. “I was in Italy when she posted it,” he says with a laugh. “She called me and said, ‘You’re going viral,’ and I said, ‘What are you talking about?’ ” He’s still getting used to the idea. “I don’t totally understand what the big deal is,” Jon admits. “But it’s humbling to see how many people connected with it.” Once he took a step back, though, he began to understand the deeper impact. “There are a lot of people out there who don’t have family like this,” he tells PEOPLE. “And something simple we might take for granted — like being surrounded by your loved ones — can be really meaningful.” For Jon, the graduation wasn’t about checking a box or earning credentials. It was about staying teachable. “I didn’t need the degree for a job or anything,” he says. “I just wanted to keep growing and stay connected to the next generation.” After more than 30 years in ministry, he saw it as a chance to better understand the conversations and struggles younger people are facing. “There are things I didn’t experience, and I realized I needed to be better resourced to support people well,” Jon explains. Ashtyn says watching her dad graduate was a perspective shift. “You grow up thinking your parents have mastered everything,” she says. “But then you see your dad doing something for the first time, too, and it’s really inspiring.” She calls it a “sweet moment” seeing him walk across the stage surrounded by classmates decades younger than him. “He just looked so proud and humble,” she says. “It was honestly adorable.” Jon, for his part, calls the moment unforgettable. “Just standing there, seeing my whole family in the crowd — that meant the world to me,” he says. For a man who didn’t want to cause a fuss, the moment became a celebration not only of hard work but of shared values. “One of the things we’ve always tried to model in our family is showing up,” Jon says. It’s not just about being there for the big events, he adds. “It’s a way of life — we try to nurture those relationships and stay present in each other’s lives.” That’s something Ashtyn has always noticed about her dad. “He’s never quiet about our accomplishments — he hypes us up, he posts about it, he brags on us,” she says. “But when it comes to his own, he downplays everything.” That humility, she says, is part of what made the TikTok resonate so deeply. “People were like, I wish my dad was like this,” she says. “And it made me realize how lucky I am.” Even Jon started to see the broader meaning behind the six-second video. “At first I thought, this is silly, people have too much time on their hands,” he admits. “But then I realized — it’s a window into what a lot of people are missing.” Jon and Ashtyn didn’t set out to go viral. They were just doing what came naturally to them — showing up for each other. "This didn’t make us closer,” Jon says. “It just confirmed that we already are.” Ashtyn agrees. “The second we found out the date, it was like, of course we’re going,” she says. “That’s just what we do.” Never miss a story — sign up for PEOPLE's free daily newsletter to stay up-to-date on the best of what PEOPLE has to offer​​, from celebrity news to compelling human interest stories. Jon grew up in a single-parent home, and building a strong family was always a priority for him. “We’re kind of the trailblazers,” he says. “And I’m grateful it can turn around in one generation.” When asked if there’s anything he’d want people to take away from their story, Jon pauses. Then, he says simply, “God made us for relationship — with Him and with one another.” And while he may still joke about “going virus,” Jon also sees the potential of these tiny digital moments. “If a six-second video helps someone feel seen or inspired, then maybe it’s not so silly after all,” he says. Ashtyn says her dad’s outlook has always shaped the way she sees the world. “He always told us that every place is a mission field — even the soccer field growing up,” she says. “So now TikTok is just another place to be a light.” Jon adds, “I just wanted to finish well — and be there for people along the way.”
