Pope Francis gave a group of children some homework to do over the holidays -- to listen to their grandparents, ask them questions and tell them about their own dreams.

"They remember history, have life experience and, for you, this will be a great gift that will help you in your journey," he told hundreds of Italian children on December 19.

The children were members of Catholic Action's children's section, parish-based groups of young people from four to 14 years of age. The Pope traditionally has an audience with them before Christmas.
