Post-Its.

I wrote out two post-its earlier and left them to their fate in public places.
I placed the first one on the mirror in the women's restroom of Barnes & Noble: "You're beautiful. Always, always remember that." Hopefully this one brightened up someone's day. The second one, I stuck to the door of some random business: "Forget regret."

All on a whim. It was liberating and fun = Happy Face.
