This is a true story: On the eve of Christmas, our car stalled in the middle of nowhere. It was raining hard, and we have no means to fix our car. Suddenly, a stranger pulls up next to us and reaches for his phone. He used an app and helped us fix our car while me and my family stayed inside, all cozy and warm. The stranger saved us from a lot of hassle and stress. I'm not sure if this is the app that he used as it was dark and we didn't see the stranger's face.
nice schoolmate! goodluck!
