Norman and Sadie both end up at the doctors - Norman because his back is breaking and Sadie because her nerves are going the same way! The doctor seems less than interested in either of their complaints.
Sadie decides that 23 years is long enough to live in a house where the bathroom is too small, the kitchen overlooked and the living is gloomy. Norman agrees because that's what he has been brainwashed to do.
When the plumber came round and left the overflow pipe for the washing machine dangling in the sink, he promised Sadie he would come back on Wednesday. True to his word he turns up on a Wednesday - two years later!
