He was not a good priest. He ended up throwing me out of the church. Not because of the Latin, though. That is a long story, for another time. When presiding at Mass this particular priest always garbles his way through the words as quickly as he can; I'm not sure why he does this, but he always does. He decided to conduct a Latin mass but didn't know I understood Latin; not fluently, but well enough for a text that is familiar anyway. When he found out he was unhappy but it was too late to back out. So I went and he did his best (in fact he did perfectly well; Latin is pretty well phonetic), and I said the responses, as you do. But he wasn't happy at all. He thought he did badly (he didn't) and that I was laughing at him (I wasn't, but he was very insecure). In all the time I was there he didn't hold another Latin mass.
