The understatement is also difficult for foreigners to ‘get’ because it is, in effect, an in-joke about our own unwritten rules of humour. When we describe, say, a horrendous, traumatic and painful experience as ‘not very pleasant’, we are acknowledging the taboo on earnestness and the rules of irony, but at the same making fun of our ludicrously rigid obedience to these codes. We are exercising restraint, but in such an exaggerated manner that we are also (quietly) laughing at ourselves for doing so. We are parodying ourselves. Every understatement is a little private joke about Englishness.
