What's Your Kindness Story?

I was at the train station, and there was this guy with serious injuries, he had trouble to walk and was carrying a kind of trolley, he had to take stairs to join his train and was in trouble with his trolley, then I ask him if he need help and carry his stuff to his train. Then he was finally seated and glad to take his train in time. I felt glad to help him, but sad as well because he thanks me a lot and just told me that was really cool from me because no one helps him usually ... I just told him that was normal and absolutely not a problem.
