Should Old Acquaintance be forgot

An unusual amount of social commitments this weekend, including putting in a brief appearance at someone's birthday party which was also attended by the MAM. I regret to say that he was offensively cheerful and still very much in lurve with his woman, who has not wised up yet and was gazing adoringly at him from across the table. He was at pains to tell me how great his new job is, how he's had loads of brilliant TV scripts approved, and that he's landed with his 'bum in the butter'.
I don't want any of that butter.
