===Eternal triangle===
{{Other uses|Eternal triangle (disambiguation)}}
"In geometric terms, the eternal triangle can be represented as comprising three points – a jealous mate (A) in a relationship with an unfaithful partner (B) who has a lover (C)&nbsp;... A feels ''abandoned'', B is ''between'' two mates, and C is a ''catalyst'' for crisis in the union A-B".{{r|pam1998|p=148}}

It has been suggested that "a collusive network is always needed to keep the triangle eternal".{{r|pam1998|p=166}} This may take a tragic form – "I saw no prospect of its ending except with death – the death of one of three people"<ref>Rose Macaulay, ''The Towers of Trebizond'' (1990) p. 66</ref> – or alternately a comic one: "A man at the funeral of a friend's wife, with whom he has been carrying on an affair, breaks into tears and finally becomes hysterical, while the husband remains impassive. 'Calm yourself,' says the husband, 'I'll be marrying again'."<ref>G. Legman, ''Rationale of the Dirty Joke'', Vol, II (1973), p. 400.</ref>
