What is a small act of kindness you witnessed recently that genuinely stuck with you?

[Always_Ethan25]

It is easy to get pulled toward focusing on the frustrating or discouraging things happening around us, but plenty of people can also point to a small, unremarkable moment of kindness they witnessed recently that quietly restored a bit of their faith in people generally, a stranger helping someone struggling with heavy bags, someone quietly paying for another customer's coffee, a kid sharing their lunch without being asked to, small moments that rarely make headlines but somehow stay with the person who happened to see them.

These moments tend to matter precisely because nobody involved was doing it for recognition, there was no audience expecting it and no real reward beyond the act itself. So what is a small act of kindness you happened to witness recently, whether you were directly involved or simply saw it happen to someone else, that genuinely stuck with you afterward?
