Not many of us get the chance to do something so heroic it makes it into the media, so it's actually the small, seemingly insignificant acts of kindness that really add up. I'm not sure why the mother wasn't capable of cleaning up the mess herself, as the language barrier should have no bearing on that, but it sounds like, for whatever reasons she was in a state of hysteria. That day, you stepped in and made a difference to that mother and child. Heroes don't always rescue people from raging rivers or burning buildings---sometimes they just clean up a mess with no expectation of glory or reward. Good job
