We would ideally remain able to laugh, in the gentlest way, when we are made the special target of a sulker's fury. We would recognise the touching paradox. The sulker may be six foot one and holding down adult employment, but the real message is poignantly retrogressive: 'Deep inside, I remain an infant, and right now I need you to be my parent. I need you correctly to guess what is truly ailing me, as people did when I was a baby, when my ideas of love were first formed.' We do our sulking lovers the greatest possible favour when we are able to regard their tantrums as we would those of an infant. We are so alive to the idea that it's patronising to be thought of as younger than we are, we forget that it is also, at times, the greatest privilege for someone to look beyond our adult self in order to engage with - and forgive - the disappointed, furious, inarticulate child within.
