"A few weeks ago, I was walking with some friends and our kids along a familiar path near my house where train tracks run. We almost had an accident as a train passed, but we quickly moved out of its way. A few weeks later, I was passing through the same area and sending voice messages to the same friends when the train went by.
I replayed the message to make sure I could be heard over all the noise, and I clearly heard the voice of a boy shouting a warning just before the train's whistle blew. There was definitely no one else on the road with me."
