The last time I did something nice for a stranger was probably a while back, a few months ago. I was walking with my mother and she was an elderly lady holding bags that were heavy and she was walking towards the stop. Apparently nobody was around to help her and I felt in a way bad. So I decided to help the old lady and as I was helping her, I asked her if she was waiting for the bus or if she was going to cross the street. She was going to cross the street so I decided to help her cross the street with her heavy bags and take it to her possible destination. That's about the lightest and nicest thing I've ever done for a stranger at the moment.
