Don't you just love good manners & grace? I feel like lately when I'm offered a seat on crowded subway car, a door held by a stranger or a kind farewell from a cab driver it really makes me want to send it on into the world. It also renews my faith in people & manners.
Consider that next time you have an interaction with a stranger...it's the little act of sweetness that can carry us to our better selves and give someone a little loveliness in the moment.
