Dialogue

This is pretty-much verbatim, a discussion I had with my PA today. I got back from a meeting, she said:

PA(ruefully): I did something very bad
Me: How bad, what was it?
PA: Someone called for you and I've completely forgotten who it was..
Me: Anything at all..?
PA: He was from Melbourne, and he seemed to know you well, and I think his name was Andrew.. he sounded friendly
Me (hesitantly): Did he sound nice
PA: Yes
Me: Oh, I think I might know who that is. I have a friend in Melbourne and he's very nice and very friendly.
PA: Oh, what's his last name?
Me (strange and guilty pause): Err... I don't know
