know, you don't a teacher just as curriculum, a coach as a playbook, you don't think of a pastor as a set of doctrines. i think the style is very important for the changes that might happen in the future. the gifts to the immigrants are a great example because here is someone who didn't just give let's say a handout of food or water, although that is a great thing, but specifically gave thoughtful gifts that come out of his street smarts. what do immigrants want to encounter people? right? they want phone cards. they want foreign stamps. they want a metro-card to get around. they want mobility that gives them a human dignity of someone who can live there in rome. so i thought this very well into a culture of encounter, which is one of this pope's biggest phrases, that he was giving a gift that would enable people to encounter their loved ones and have some sense of family stability even though they'd immigrated to rome. in short i think the style changes are very, very real changes when it's a pos to recall leader. >> and there's been some concern
