Hello!  Watching this TED Talk is one of the neatest ways I can suggest that you spend 12 minutes of your day in front of the computer—or whatever screen it is on which you are reading this.  Charlie Todd is the creator of Improv Everywhere, a group that creates absurd and joyful public scenes.  He cares about providing positive shared experiences for people, particularly strangers in public places, and I have immense respect for him. 
I hope you enjoy this video and maybe take some inspiration from it!
