HUBERT: Yes.
OLIVIA: I've never heard you make a joke before, Hubert.
HUBERT: Didn't realise it was one till I'd said it. Sorry.
MRS. BRAMSON: It's not a joke; it's a libel.
A knock at the front door.
Come in.
NURSE LIBBY enters from the front door.
The boy's a teetotaller.
HUBERT: Sorry; my mistake.
NURSE: Good afternoon. Shall I wait for you in your bedroom?
