Say Something Nice
I absolutely loved the lady who didn't hesitate in stepping up to the mic to say, "Hey, you with the umbrella...the blue umbrella. I really like it. It's pretty". Even something as trite as "Have a nice day" might've even made somebody's morning.
Now if only people tried to say something nice everyday and paid that forward, imagine just how much more peaceful and loving the world would be.
Bravo, Improv Everywhere.
