One knock. One sentence. One ordinary Tuesday that almost never happened. 18 years ago, Lexi was sitting on her bedroom floor with a goodbye letter. And then her brother knocked on the door.   What if the moment that saved your life didn’t feel heroic at all? This is Lexi’s story — a sister who almost didn’t make it to see her 18th birthday and a brother who showed up at the exact moment she needed him most. Eighteen years later, she’s watching her daughter laugh in the sun — and realizing that one knock on her door created all of this. This episode is about the power of paying attention. About what happens when someone sees you — really sees you — before it’s too late. It’s not a story about suicide. It’s a story about survival. About noticing. About what can still grow after a storm. Because the life you think doesn’t matter might become the anchor for someone else’s joy.
