Heidi is very 'mumsy' and constantly refers to her seemingly idyllic domestic situation, to the near-universal annoyance of the other characters. It is clear that her home life is not as perfect as she believes. She repeats highly critical comments Keith has made about her as though they were kindly although she occasionally seems doubtful about his more extreme political views. He hates foreigners, is homophobic, thinks the police should be armed with laser guns that can paralyse and believes Heidi is more than enough female influence for his son. He also encourages Heidi to act out his bizarre sexual fantasies to make their sex life more interesting for himself.
