Having four characters, all of whom are very different and occupied by different bits of my brain is incredibly useful. It gives you information about two different characters in one very short sentence. And she's got a lot of deadpan irony. I don't know whether it's her irony or whether it's yours. Here's another one for you that you'll know. Once you've done the oysters, there's no wheel shopping to speak of. Now, I mean, is it your irony? Is it Joyce's irony? Well, listen. I have to accept a course somewhere deep down its mind.
