Like millions of others around the nation, I've been left feeling raw and shaken by the tragedy at Sandy Hook Elementary.

We're all familiar with evil in this world, but sometimes the extent to which it plays out is even more heart-wrenching than we could have imagined. As a parent of small children, this horrific event in particular rocks my soul. You feel for the families of those lost — and yet, even then, it's a helpless emotion.

Perhaps the best response I've heard of this week is to act to make the world around you a bit better. Two days ago, NBC News Anchor Ann Curry took to Twitter to announce that she was committed to performing 20 acts of kindness to honor each child lost in Newtown. She asked her 1.3 million followers if they would be interested in doing the same — and the wave of support quickly grew, with the 20 acts increasing to 26 to honor the adults also killed in the shooting. Below are some of the inspiring tweets she's received back.

Search for #26Acts on Twitter and you'll find that more than a few times every minute, someone is posting about a random bit of kindness they've done today — with many more to come. It's through gestures like this that we can in some small way honor the memories of the children and teachers lost at Sandy Hook Elementary. How will you change the world around you?
