By now, the internet is flooded with photos of him before, during and after the conclave. The only description I can find is "small and simple". Here are some photos from before the conclave.
His mode of transportation
On board the bus
Visiting the needy
Washing and kissing the feed of youth
Kissing the feet of the disabled
Drinking his favorite beverage
I think we can conclude from how he ministered to the christian community in Buenos Aires and his actions since being elevated to pope - personally paying his hotel bill, riding the shuttle bus with the cardinals, celebrating 7 am mass with the Vatican workers, to stopping the popemobile, descending and going over to bless and embrace this man ....
.. and now learning that he does not want to reside in the papal apartments, that this pope genuinely embraces poverty, humility and has a pastor's heart.
God has sent us the right man for our time.
