As a child if was breakfast - always a fry-up, dinner at school, supervised by dinner ladies, and tea at home after school, usually something on toast, boiled egg, and a pudding such as apple and custard. Supper would be cereal or a snack with milk before bed time. Now it is breakfast - coffee and toast, lunch (maybe a sandwich or light meal and fruit), and around seven it would be dinner. Probably nothing before bed, or maybe decaf coffee and biscuit. Afternoon tea these days would be a rather pricey treat in a hotel or similar with finger sandwiches and dainty cakes. The loo is always called that, as is loo paper, the room we sit in to watch TV is the sitting room, and always was. My daughter, who lives in Surrey, not too far from us, calls their evening meal supper, and I got told off recently for asking her 3 year old what she'd like for dinner (I may have said din dins) as I have always used that word for small children. Oh heck, does it matter? Vive la difference and long live dialects and regional ways of referring to things. It makes our language so charming and reminds us of different historical influences on our language.
