30 gifts to 30 strangers video via Operation NICE. It brought a tear to my eye. When you are living in a foreign country, you appreciate SO much the niceness of strangers. You are far away from friends and family, and when someone goes out of their way to do something nice to you, it makes this strange faraway place feel a bit more like home. I come from the overly friendly Midwest, where everyone is generally nice and helpful. You take it for granted, until you realize the whole world isn't like that.
I love the idea of turning it around and saying thank you to strangers.
