After a journalist reported on Pope Francis’ surprise visit to a record store, the Pope surprised him back — by writing him a letter.

Javier Martínez-Brocal, director of the Rome-based news agency Rome Reports, tweeted a black-and-white photo of the Pope exiting a record store near the Pantheon in Rome. The photo went viral as people wanted to know, “What did he buy?” The journalist also captured video of the encounter.

But while the Pope left the shop with a disc, he came for another purpose: to visit the owner, an old friend of his, and to bless the newly-renovated store.
