Share a time when you or someone else did a simple random act of kindness and it brightened your day 🥰

When my brother and I were very young we use to love to ride the animated coin activated children's carousels near the entrance at the grocery store.
I remember our mom finishing with buying groceries and my brother and I ran a head to hop on the little animal figures just waiting for her to catch up and feed the machine some coins. A stranger man walked by and put some coins in and started it for us, I was in such surprise by his kindness Ive never forgotten. 💗
They dont have those kids rides anymore, my guess they have become safety hazards?
