Who is Stuart and Pat from London Transports and what is their importance? London_Transports English & Literature Stuart and Pat | London Transports

A married couple who respond to an advertisement for a wife-swapping party, Stuart and Pat live an average life with their young children, Debbie and Danny, a life largely centered on gardening. Their sex life is ordinary. Stuart is blasé about the evening as it nears, but Pat panics. It is the "Terrible Day" for which she has her hair styled and worries in the mirror about how deadly white her skin is. She sees herself being rejected by all of the swingers—equally worrying about being ravished. Stuart assures her that because they are doing it together it is not infidelity but rather a generous sharing and exploration of new pleasures. Pat worries that their escapade will become known and ruin Stuart's career at the bank and their children's reputations. She worries about Stuart's intentions when he wants to take the train rather than having to worry about being in condition to drive home.
