I would ignore the bowing thing, since I don't understand what that means, and I would invite him in and offer him a cup of tea or coffee. I would also ask why he was visiting me. Then I would ask if I could ask him a few questions, such as:
1) Why do seem to believe that traditionalists are Pelagian? Have you tried to understand their concerns?
2) Why do you believe that the changes brought about by the Council are a good thing?
3) Are you aware of the importance of the Papacy, and that as Pope you are called upon to proclaim the truths of the faith in a clear and unambiguous manner?
4) Why did you not allow the TLM to be properly celebrated in your diocese in Argentina? Yes, I'm aware that it was celebrated, but lay lectors gave Novus Ordo readings, which goes against the norm for the TLM.
5) Do you believe in the Real Presence?
6) What changes are you planning to try to implement in the Church?
IMO, Pope Francis does not take his job seriously. It seems like a game to him, and he's quite childish as times. Maybe that will change and it will dawn on him that he's the leader of Christendom, and that as such, he has great responsibilities. Though it's possible that he has a modernist agenda that that he DOES take seriously.
