What’s a moment when a stranger completely restored your faith in people?

Well as a person who have been through a lot of injuries of different kinds, I think the one time that restored my faith was when I were walking on slippery ice on the way to school and I felt hard and hit a sign post. No one cared at first even I was clearly in pain, suddenly a pair of hands took hold of me and told me ‘you are going to make me miss my train but you seem like a person in need’ so he half carried me about 1 km to my school and made sure that someone was there to continue taking care of me. I offered to pay him a new ticket but he was like no thanks, I did this full aware of that.
