Breakfast was the meal we ate in the morning. Lunch was eaten half way through the day and tea was eaten in the evening. Dinner was the largest meal out of lunch and tea so Sunday Lunch was eaten in the middle of the day but Sunday Dinner could be eaten at lunchtime or tea time.
My Grandad was the only person I know who had a supper which was always cheese and Jacobs cream crackers* before he went to bed.
But we are Suverners so what do we know?
*My Grandmother continued to buy cream crackers after he passed. When she went into a home, she had shelves full of them.
