Also, Adrian's relationship with his son William's nursery teacher, Mrs Parvez.
When Adrian asks if the anteater on William's coat peg might be substituted with something more cuddly or lovable, she replies coldly "I have three left: an elk, a gazelle, and a warthog."
Adrian is determined to prove Mrs Parvez wrong about whether birds sleep in their nests. She refers him to an exact book and page.
At a farm visit, William claims that a goat ate his lunch, and the box as well. CCTV reveals that William threw the box at the goat.
"William said he did it because the goat looked hungry, he's such a thoughtful kid. But it has to be said, he is also a convincing liar. I told him the story of the Boy who Cried Wolf, and that if he didn't behave, a man called Jack Straw would get him and put him in prison."
And how does Mrs Parvez get her revenge months later? By making William play a goat in the nativity play! Adrian notes that goats never appear in any nativity scenes.
Another brilliant part was when teenage Rosie is pregnant, and is given a crying electronic baby to look after, which looks like a prettier William Hague, and is of indeterminate sex. Rosie eventually hurls this doll out of the window, and has an abortion. Adrian foolishly accompanies her there, and notes that it's not a good place to be a man. When Adrian's mother is upset for Rosie, Pandora's father quips "Pandora had a termination in her lunch break once, there was none of this bloody hysteria". And the icing on the cake is when Adrian returns the doll by post; it starts to cry, and the colour drains from the postmistress's face. Adrian says "do you really think I would send a live baby by Parcel Force?"
