A、That he’ll be performing in a concert. B、That he had a conversation with the director of a choir. C、That he’s been translating

M: Hey, Ellen, you’ll never guess who I met last week. Barbara Johnson.
W: You don’t mean the Barbara Johnson who directed the choir that performed on campus last weekend?
M: That’s right.
W: But she’s so famous. How did you get to meet her?
M: Well, you know how in that program they handed out, they printed the words to the choral pieces a long with the translations. I found all these mistakes in the Latin text, you know typographic... Wait a minute.  You were actually reading the words.
W: I like to follow the text while I’m listening. It helps me understand what they are singing about. Any way, while they were doing those Latin pieces.
M: I notice all these mistakes, mostly spelling errors. It was really annoying. So after the concert all those people were crowding around back stage to see her and the soloist...
W: Yeah, I remember there were dozens of people waiting there for autographs.
M: Well, I waited to the end, and then when I met Barbara Johnson I showed her the mistakes I’d found.
W: Was she upset?
M: Upset? She actually thanked me and said if I sent her a copy of the corrected text, she would revise it for the next time they sing those pieces and even print my name in the acknowledgement as a pro gram editor.
W: Wow, your Latin must be pretty good to find all those errors.
M: I should hope so. I major in classics, you know.
