- I know, darling, I know. We've been very busy.
- Get on with it. Get on with it, you mug. That's what you're here for.
- Well, we're not busy now, are we?
- Is it, darling? I didn't count!
- Well, I think I'll be turning in, darling.
- Yes, I think I'll turn in, too.
- So am I.
- I don't wonder. I'll just go and count the cups.
- Yes, darling. I always count the cups before bed.
- Look here, this is intolerable!
- Yes, I quite agree, but what can I do? Everything's failed.
- Have another go. Try as you've never tried before.
- All right, for what it's worth.
- Shut your eyes. It'll help you to concentrate.
- Oh, of all the caddish tricks. I can't think what's come over you.
