Lately I've stumbled upon all kinds of sweet things people are leaving for others. First, these painted rocks left on a beach, encouraging folks to take one, then return with a painted rock to pass on to someone else, a collaborative kindness project of a Girl Scout troop and artists from a local art gallery. In Hartford, we walked past a church with beautifully colorful handcrafted scarves hanging on the fence out front. Each had a little tag that encouraged anyone who was cold or who knew someone who was cold to take one. And yesterday I passed two tiny "free libraries" full of books and a welcoming sign urging passersby to take something to read. It made the world seem that much warmer.
