It’s hilarious how people are so ingrained in their culture that these things affect them so much. Like if I ate a roast dinner for breakfast or took a shower every lunch time, I’d be considered a madman.
It sounds absolutely silly but really there’s few good reasons for most of our habits.
With my Anglo/American breakfast habits I was kind of shocked that traditional Japanese breakfast includes a full range of fish, rice, soup, salad and more or less anything else normally eaten. I probably feel as strongly about breakfast being mild or sweet flavors as Italians do for cappuccino after 11 and for no better reason.
We'll wait, what are you calling 'curry'? Because British kedgeree (as kedgeree is) is distinct from what any Briton I know would call 'curry' - even given the disservice we do India by calling almost everything 'curry' - and further distinct even from khicadi (खिचड़ी) from which it takes its name, and moves to breakfast.
