In the United States, in 2024, a young woman posted a video to find a former elementary school classmate she had not seen in years.
Social media has long been used to find old friends. TikTok does not invent the principle; it changes the format and the visibility.
Users post their old class photos there, hoping for news of people they have not seen since childhood or adolescence.
On TikTok, the mechanism remains the same as on older sites: share a collective memory and let former classmates come forward.
Some of these images accumulate hundreds of thousands of views. In the comments, users sometimes recognize one another.
The two women eventually reunited twenty years later, thanks to social media.
The phenomenon is part of a wave of nostalgia currently visible on social media, where school photos serve as a point of contact.
The episode illustrates what these platforms make possible: a photo, a question, then sometimes a recognition in the comments.
