So what are they talking about at the World Meeting of Families?

The World Meeting of Families is focusing on key issues related to family drawn from Pope Francis’ teachings in The Joy of Love (Amoris Laetitia).

The Congress has been described as "a joyful and enriching occasion for adults, young people and children ... to meet and share, pray and reflect, grow in faith and love, celebrate, as well as gather strength to continue the journey of life."
