N'kay - breakfast, dinner tea...I think maybe this tells us something about Lancashire...
'Coz where I am, here in the prairies of SW Washington State, we are clearly more sophisticated...WE have breakfast, lunch and supper EXCEPT on Sundays when you have a later breakfast, and then a big meal around 2 PM which is called Sunday Dinner. So much food that it fills you up for the rest of the day, until maybe early evening when you might do some snacking on the leftovers from the Sunday dinner!
...and of course, the way we do it right here in the SW Washington countryside, this is obviously the RIGHT way...I mean, these fellows do not even mention the possibility of something called supper...sheesh!
