You bumped into an old acquaintance and suddenly realize your kids have run off without you noticing. You get a call in the middle of the night with probably some of the worst news a parent can hear and wonder what to do next. You are watching one of the country’s worst terrorist attacks unfold hundreds of miles away from home and feel utterly alone. These are moments we hope to never find ourselves in. But they are also moments when unexpected kindness, compassion and understanding can transform our views of humanity. For this month's One Question, we asked to hear stories of the kindest thing a stranger has ever done, from small gestures to large favors. Here's hoping these heartwarming stories may remind you to pay it forward with a good deed.
