I was brought up in a class/culture that talked about breakfast-dinner-tea as the meal order of the day.

Since then I have spent a lot of time in the breakfast-lunch-dinner world.

So now I talk about breakfast-dinner-dinner — and thus am annoying ambiguous to everybody.

My apologies.

@adrianh As I was growing up, "tea time" on beach vacations was when people had gin and tonics. Generally about 4:00pm on.
@gdinwiddie Oh don’t get me started on the distinction between “tea” (the 4pm cup of tea and biscuits, or if visitors cake) and “tea” (the evening meal).
