Friday night is a cocktail evening. There's already a bewildering and lethal list forming, not to mention reckless talk of consuming digrizfizzes, and even "Swagger Slings". The latter contains:
1 bottle champagne
1 bottle claret
1 glass brandy
1 glass Grand Marnier
Apparently (quoting Kingsley Amis, whose "Everyday Drinking" I am ... er ... working my way through) the Swagger Sling tends to "put young ladies completely at their ease".
