The process is call rapport building. That’s what he was doing with Melania, by referencing a delicacy from her homeland. It’s a crying shame that liberals are so fucking desperate for things to rag on Trump about that they totally lose sight of reality.
Minus the insulting bits, I’m with Clothahump on this one. Pope Francis is a diplomat and a gracious person. It’s clear that he was putting Melania at ease.
I have seen nothing in Francis’ history or demeanor to suggest that he would ever publicly ridicule a guest.
