Freddie: So, how was your bath?
Effy: What bath?
Freddie: The one you popped home to take about three months ago.
Effy: Right. I went to Italy.
Freddie: Italy?
Effy: Si. How was your summer?
Freddie: Not bad. Got chlamydia.
Effy: Wow. Exotic.
Freddie: That’s what I said! Then I realized Cook had it as well and didn’t feel quite so special.
Effy: I bet it liked you more. So, who gave it to who?
Freddie: We didn’t. There was an intermediary.
Effy: And you’re all… clear now?
Freddie: Oh! Yeah. Fine now. Clear as a bell. Not sure about him, though.
Effy: It’s you I spent all summer thinking about.
