"That's the beauty of life, we can find joy in the most unexpected and smallest places and moments."

This! SO much this. The best part is situations like you described on the bus; you were just going about your day and someone did something good for you, then you were able to pass that on and do something good for someone else. Just taking the time to appreciate the gesture and reciprocating makes a huge difference in the world, even if we don't see the big picture.

Thanks for the post!
