(Vatican Radio) For the second time in two nights, Pope Francis greeted crowds outside the Apostolic Nunciature in Mexico City on Saturday.
After returning to the residence after his busy Saturday, the Holy Father heard the crowds and came back outside.
He asked if they people were tired, and they shouted "No!"
"We could go until 4 a.m? But that could be a little long," Pope Francis said.
The Holy Father said he thought someone had a problem of the heart, and asked the crowd to pray to the Virgin Mary.
"The Virgin is a mother, and is good...a few might say she is not like a mother-in-law," he joked.
Pope Francis then led crowd in a Hail Mary, and encouraged them to take their problems to God through Our Lady, before returning to the residence for the night.
