afternoon tea: is it still done?

[Lallans]

After international misunderstandings within my family regarding the meaning of 'tea', I fell into a sort of code where 'tea' when addressed to a British person meant 'supper' (ie, to the Scottish plus the Northern England and Northern Ireland members), as per their usual practice, but I employ the term 'high tea' instead of 'supper' when addressing a mixed group, as in an email "Thank you for giving the kids the lovely high tea" . This is probably seen as a little pretentious on both sides but it works. 'Tea' meaning a meal is of course never used in my part of Canada: rural people say 'breakfast, dinner, and supper' and perhaps more recently use 'lunch' if 'dinner' is a light meal, whereas city folk have adopted the more American terms of 'breakfast, lunch, and dinner.' This is seen as more sophisticated than 'dinner' followed by 'supper' but I am seeing signs of a Canuck backlash back to 'supper'. And don't get me started on the use of 'brunch' and its variations.
