Have you ever received a kind note from a stranger? via /r/gratitude

A while back, I was sitting in a cafe, just trying to get through one of those rough days. I wasn’t really paying attention, just staring out the window, when I noticed a small folded piece of paper under my coffee cup. I unfolded it and found a few handwritten words: “You’re doing better than you think. Keep going.”
I looked around, but it wasn’t obvious who had left it. It felt like a message from the universe at just the right time. I will forever be grateful to whoever left this for me.

I kept that note for months, tucked in my wallet. Whenever I felt off or doubted myself, I’d pull it out, and it would remind me that I was on the right path.
One day, I was at the bus stop. There was a woman there looking exhausted, like she was carrying the weight of the world. She looked lost in thought, staring off into the distance. Without much thought, I slipped the note into her bag as she walked by, hoping it might make her day just a little easier, as it did mine.

I don’t know when this note started, but I hope it keeps traveling, passing through more hands than mine. I like to think that kindness, even in the smallest form, can travel further than we know.

Has anyone ever left something like that for you? A small act of kindness that stuck with you long after?
