You posted something — a photo, a comment, a video — that you thought was harmless. Maybe a joke that didn't land, an opinion, an awkward moment. And it took on a life of its own. People shared it, screenshotted it, talked about it. Suddenly that one post became who you are to half the school. The thing people brought up. The label attached to your name. You've changed, moved on, would never post it now. But the internet doesn't move on as easily as people do. The post is still out there, still resurfacing, still introducing you to people before you get to introduce yourself. One moment, frozen and shared, has somehow become your whole identity to people who don't know anything else about you.
