A grassroots wave of people across the United States are performing millions of acts of kindness to honor the memory of the victims of the Dec. 14 mass shooting at Sandy Hook School in Newtown, CT., after a single tweet by a national journalist.

“Imagine if all of us committed to 20 mitvahs/acts of kindness to honor each child lost in Newtown. I’m in. If you are RT #20Acts,” was the tweet NBC News’ Ann Curry sent out soon after the shootings.

Within hours, thousands of people had tweeted in response; it quickly grew into 26 acts of kindness, to honor both the children and adults who died at the school. In a blog post, Curry said that there was some debate to make it 27 acts, to include Nancy Lanza, shooter Adam Lanza’s mother. Some even suggested making it 28, since Adam himself was struggling with mental illness.

The popular sentiment of 26 acts of kindness stuck, however, and over the last couple of weeks has gained in popularity. Besides the official 26 Acts of Kindness Facebook Page, many more unofficial pages, or pages for specific communities, are springing up. A Twitter account was also established, @26acts.

All over social media people are reporting their acts of kindness, from handing out cash to strangers, to paying for people’s coffee or meals, to baking cakes and cookies for others, to donating money to organizations, and much more.
