Tonight we're noticing something very positive across the country in response to this story. Reporter: An overwhelming river of giving now flows freely through the newtown post office. Some send prayers, others much needed support. From washington and far beyond. I think I saw brazil, australia, anybody in newtown needs a hug. Amazing. Reporter: In the town hall, a mountain of donated toys is piling up just in time for christmas. Even hurricane sandy victims are giving hundreds of teddy bears. Basically we had so much help, we wanted to pay it forward and try to help somebody else. Reporter: Newtown wants others to pay it forward now in honor of the victims. From a secret santa in pennsylvania to new jersey, where kristin went shopping for ingredients, only to find a target gift card hidden in her cart with a note asking her to pay if forward in honor of sandy hook shooting victim catherine hubbard. It really made me stop. I was frozen. It made me think about that little girl. Reporter: Inspired, she paid it forward by giving the gift card to her bank teller after making a deposit. How has this one act of kindness changed you? It really made me think of the bigger picture and family and friends and, you know, really extending the kindness to strangers as well. Reporter: Her hope, those moments of terror inspire you to join in next, for 365 days a year. Mark greenblatt, abc news, new york.
